I'm not sure why, but when i'm drunk little things in general seem to really annoy me.
Went to a bar, everyone inside, me and a mate get a pitcher.
Then everyones outside waiting to go. I'm like hang on, just got a drink here. Then the group walks off.
Normal I'd be like ahh well, i'll catch you up but when i'm drunk it's suddenly a big deal and i'm saying if they want to leave us, we'll not tag along with them all night and do our own thing.
Unpolitely.
Is it your first time getting drunk? What you describe is pretty much how most nights out go for me. We end up doing our own thing but nobody is any worse off really. You have to remember that the others are the same as you, ie drunk. You might be going 'hang on ffs' they might be going 'come on ffs'
