P-C, wouldn't this be the "find him a bride in India" trip?
No, we're going for a cousin's wedding.
To be frank, I don't see how these are mutually exclusive things.
To be blunt, you are out of your everloving mind if you don't think your mom is going to spend every minute of this thing a) trying to get you married; b)moaning that you aren't married; c) implying that you are horrible and killing her by not being married; and d) actively stating that you are horrible and killing her by not being married.
If you REALLY want to go to your cousin's wedding (I always do, my perpetually un/under-employed self has a credit card that is pretty much dedicated to this once or twice a year occurance) you buy the tickets and book the room and hang out with your family and ditch them sometimes too. She'll bitch and she'll even look right when she does what with you being an independent person and not hanging on her every moan. If you really want to go to your cousins wedding do it as a grown up who makes a nice living and pays his own way and know you'll piss her off. If you really want to go though, go.
