I have said here before that I think weddings are (or they've become, rather) the epitome of what's wrong with America.
Americans have become narcissistic, greedy, Attention whores who lack any grasp of the "bigger picture."
Yep, no one gets married or has extravagant weddings they obsess over outside of the US.
In regard to the OP, I'm torn between my disgust at the friend for going on the radio and making what should have been a private discussion between friends into a public spectacle and the bride's extreme selfishness and rudeness towards her friend's pregnancy. Neither of them seem like very good friends to each other, but the bride obviously comes off worse because of her reaction.
