Who’s Getting Married Anyway?

I don’t understand the whole bridesmaid thing. Why as a bridesmaid must I bare the expense when it’s your wedding? If it was just a $50 dress, maybe it wouldn’t be so bad, but when you’re talking $150 dress plus plane ticket plus hotel room plus rental car plus hair and makeup the way you want it plus shoes…..I’m starting to wonder who is getting married. I know weddings are expensive but I just get perplexed at the part where the bridesmaids bare some of the expense.
