god fucking damnit i need to go to my cousin's wedding in about an hour, on my one day of weekend after a 65-70 hour 6 day work week, only one day of weekend and start all over again tomorrow 
god fucking damned assholes with their marriages make me wanna smash their face to bloody pulp
i'd rather go bang arms on friday night with everybody admiring me in the gym

OK, I know you're no fan of me, but let me ask you a serious question.
Why bother going to this wedding?
Seriously, it's obvious you dread going and it's only your cousin.
You work long hours and deserve to do what you want when off.
Why get mad? Just blow it off and do what you want. Fuk it, if they don't like it.
