If someone said.....

[AndTime]

We'll go the gym at 11.......

Would you expect to leave home at 11

Or

Be in the gym at 11

I think it depends on why it matters. If the gym had timeslots or classes with particular starting times, then it would make sense to specify the time that you intended to be there. If someone was doing something at home that had a particular time constraint, such as cooking something or watching a video, then it might make sense to specify a time when they were free to do something else, and in that case the getting dressed to go and travelling time might all be lumpled together in the category of something else.

Having said that, as the only driver in my home, if I said we're leaving at 11.00, I would expect that to be the exact time the car wheels start turning. Not the time you expect so start putting on your shoes. (But this is different, as I would be specifying a leaving time, not a time to be at the other place.)

'We'll go to the gym at 11' = 'We'll leave at 11'

Otherwise, it's 'We'll get to the gym at/be at the gym for, 11'

I would have said it meant leaving at 11 living in same house.
But would knowing me asked what time we aimed to be there for

Either, both. Would clarify at the time?

I’d expect to go (to the gym) at 11. So leave the house at 11. If someone wanted to be at the gym at 11 they should specify ‘we’ll leave to be at the gym at 11’.

If going from same place together I would think this meant to leave at 11. Otherwise would be for or by 11 and I would say 'so be ready to leave at half ten or whatever'

Poor communication skills on his part IMO. If you're going to 'go' to the gym at 11 then you can't be at the gym can you? How long does it take to get to the gym that not leaving till 11 messes all his plan up and he now has to eat???

Leaving at 11 from the same house.

Living together I would take that to mean leaving at 11

"Let's get to the gym for 11"/"Let's arrive at the gym at 11" or "Let's go to the gym at 11"

@AndTime

Sorry should have clarified that, we are in the same house, leaving together.

Leave the house at 11ish then.

Leaving at 11 if you live together.

Leave at 11, if love together. If not I'd say meet you there at 11

Tbd it doesn't matter what anyone else would think, unless you are having some kind of mass gym visit

It's a miscommunication, no biggie but how did he not realise that you weren't showing signs of being ready to leave, do you live in a massive mansion?

He keeps doing this. Says one thing but means another and when I am not a mind reader to know what he actually means then he gets stroppy.

Why does he have to eat again?

I’d probably ask which one they meant, be there by 11 or leave at 11, rather than just assume.

Me and DH tend to specify “we’ll get there for 11” so that things like this don’t happen.

@SandysMam

Why does he have to eat again?

No idea. The gym is only 10 mins away anyway so I don't see what difference it makes anyway.

He was saying cos if we leave at 11 we won't get there until half past. But the gym (including his errand) took us ten mins to get to.
