AIBU to find my friend's behaviour rude and increasingly irritating?

You didn't say whether or not he gave you a gift. It could mean that he ate your leftovers so if you bring that up, he'd say "Oh, I didn't even let you cook anything special for me..." He's puerile. Why don't you tell him where to get off? Is he supposed to be taking medication, and he did not?

How so?

Is it possible that he fancies you? Wants to feel very close, hence eating your leftovers from your plate. Performative voices- just trying to be funny to impress you.

How old is he OP?
It's definitely strange behaviour and clearly he hasn't been this way your entire relationship. Could it be the start of dementia do you think or a medical issue?

Thank you. I'd say he sounds like the epitome of someone doing drugs! That partly explains his peculiar ways.

Is he having a mental health crisis? It's certainly not normal behaviour.

This actually makes sense to me. I'm having flashbacks to a dinner party I once went to the night after I went clubbing (drugs were involved). I got through it without any of your friend's deranged behaviour but I can absolutely relate to the feeling of alternating between ravenous (eating all the starters... I'm guessing these might have been quite hangover-friendly) and queasy.

It's good that he recognised how weird he was being and that he apologised!

As for the night out and drugs, you'll get the usual crowd on this site telling you he's a useless junkie and you should never talk to him again, but I assume you know him better than we do and have an idea of whether he's an occasional party boy and has it under control, or whether he's going off the rails a bit.

Just tread the update. Weird thread. You write like AI by the way.

Why is he your friend? How long have you known him? How old are you both?

That sounds like a control thing. It is weird. Just repeat your instructions next time. What would you like to eat. No, I'm not comfortable with you watching me eat and that was a strange request. A few of us have noticed some odd behaviour from you, is everything okay?

Obviously, don't be alone with him in your home while confronting him.

His behaviour is odd but I think you pandered to it too much with the food. I’d have plated up two meals, and served myself what I thought I’d eat. If he didn’t want his plate of food that’s up to him, I would have left it on the side and eaten mine. For you to just eat a tiny bit and then hand it to him because you knew it was the only way he’d eat is equally odd to me- he’s a grown man, it’s not your job to ensure he’s eaten at the expense of your own meal! Did you then get up and get yourself more? Do you actually like his company, when he’s not being weird about food or making odd noises?

How did he know you’d have any leftovers if you made one portion? I’d have been eating every last drop and wiping the plate clean so he didn’t have the opportunity to behave in this bizarre way.

If he’s using up his annual leave suddenly and taking drugs what else is going on in his life? He sounds like he’s having a MH crisis of some sort.

and before I got to the update any behaviour like that from someone I know well whose never done it before I would attribute to drugs.

I would nor have let him eat from my plate that is really really odd behaviour. If he tries again to ask for this tell him you find it a bit of putting and won't be giving him your leftovers. I'd either scrape into the bin or just eat everything on my plate.
As for the bizarre behaviour is this normal for him or new. I'd be worried that something is seriously wrong with him. He doesn't sound like someone I'd be friends with.

This.

So drugs is the answer to all of it then

Yeah that’s really odd.

This sounds bizarre . Anyway its kind asking a friend what they want to eat when inviting them over, but it was your birthday as so maybe should have chosen what you wanted and just said i am cooking this for my birthday. Do you want some?
the not tidying away after …is this somethjng he used to do before?
you could say, next time you invite him over, if theres a next time, do you mind clearing the playe away to the kitchen when you are done
optioms - dont invite him over for food anymore
can you do somethjnt else instead? Go out for dinner or meet for a coffee
the bike noises - ask why are you making yhese bike noises
have they got somethint going on in their life and this behaviour is a result of it?

I want to hear the other examples of his behaviours now just so I can try to work out if they seem drug related or not! 😆

Is he a dog eyeing your plate for leave that's just plain weird.
What if what you made and you're enjoying and want to munch it all.
CBA arsed with him to be honest.

So he’s on drugs. Great. Back away.

Depends. Did he bring you anything for your birthday or turn up empty-handed?

Op I don’t get it there are so many people gas lighting you on here when clearly he was being bizarre. It’s not about how many options or no options or questions you gave him, or whether you ate anyway, your behaviour here is not the issue! I wonder if he’s doing it to gain some kind of control/power as a sort of behaviour disorder. It is ringing bells with me of the way kids do odd things to wind you up when psychologically what they’re doing/wanting is getting your attention because they want affection. Sometimes people who have had insecure attachment in the first five years of life, as an adult if they subconsciously notice someone pulling away, they will dig their claws in in some way, as a sort of self sabotage self protection method. That chime at all? Either that or drugs?! 🫠

The card still wouldn’t inspire me to invite him back any time soon, I’d also be wondering how many drugs he’s taking. I wouldn’t be close with someone who uses drugs regularly.

I wonder if he is taking drugs more often than the once and you are picking up on the changed, weird vibes and it's giving you the ick.
