I suspect I am, as if it were one of my friends I'd probably feel slightly different (although timing still sucks) but... [shrug]
About 18 months ago DH became friendly with a couple (I'll call him A and her B) who at the time ran a shop in the village. They are about my age, early 40s. We socialised as a foursome a few times by which time I came to the conclusion I didn't want to spend my precious free time with them if I could avoid it. There's no way of explaining why without coming over as a crashing snob or an old fuddy-duddy - which is fine, I have elements of both. 
They have a very 'teenage' way of behaving - A is 'obviously' immature; his only hobbies AFAIK are skateboarding, computer games and getting drunk and/or stoned. I know I am judgy about the latter (privately - I don't discuss it with him) partly through natural anti-drugs inclination and partly because I used to work in the criminal justice system. He has two school-age DSs from a previous relationship who he never sees despite not living very far away from them. I get the feeling he's too busy trying to be a teenager to have time to be a father. B always has to be the centre of attention and whatever anyone has done, she's done it bigger-better-faster-stronger. Nights out with them invariably involved them racing to get from 0-drunk as fast as possible then having very melodramatic arguments, slamming doors, flouncing out, tears, swearing, shouting, then equally OTT make-ups. I found this neither enjoyable nor relaxing.
About a year ago I signed up for an industry-specific training course. It's been very enjoyable but also very full-on: loads of self-study which I've fitted around full-time work - essays, presentations, other assignments etc. It also became the perfect excuse for me to drop out of nights with A and B pleading too much study. A little while after that their shop closed and B got a job involving evening shifts, so a routine evolved whereby my DH and A would go out maybe once a week/once a fortnight. My DH knows I worry about him drinking too much (he's on a cocktail of medication for a chronic health condition and too much alcohol isn't good for him) so when it's his turn to pick the venue he tends to suggest they play pool to slow the drinking down a bit or he alternates alcoholic and non-alcoholic drinks, but invariably A will buy DH a pint when its his round regardless of whether DH has asked for a soft drink, teases him for being a "lightweight" etc. (He knows about DH's health issues and meds.)
My course finishes next week - I have to give a timed presentation on Monday morning followed by a 3-hour exam in the afternoon. If I pass this course well, I'll get a bonus and a pay rise. I've taken this week off specifically to work on and rehearse my presentation, to do some general revision and to clean/tidy our spare room during 'study breaks' ahead of my DSD coming to stay with us next Tuesday (she's staying a week so she can see DH on Father's Day, and she lives nearly 300 miles away so is making a nice proper break of it).
Today A has sent my DH a text to say he and B have split up again and asking if he can stay with us for "a few nights" to "get his head straight" and has signed off with "I'll bring the beers!" I really, really don't want him here. I'd have to spend the rest of today tidying the spare room in one go (I'm not a complete slut, we just haven't had anyone to stay for a while so have been using it as a bit of a dumping ground for eg suitcases, winter bedding, my DH's art stuff etc so there's some stuff to find homes for plus the usual hoovering/dusting/bed changing etc) so won't get any studying done, and then will have to clean/change it all again for DSD coming. More importantly he'll be here underfoot the whole time I'm trying to rehearse my presentation and revise for my exam. DH isn't mad keen but feels he should help out a friend in need; I really want to say flat-out "no".
Aaaaaaarrrrrgggggggggggghhhhhhhhhhhhhh!!
