Should the bridesmaids write thank you notes to the parents of the bride, since they paid for the wedding? It was a pretty lavish affair (and holy cow, the bride was stunning!), and we were well looked after. Champagne and snacks while getting ready, exceptional hair and makup artist, and everyone made each of us feel like a princess even though it wasn't our day. 
I'd like to send them a note, I just don't know if it would seem weird.
