I thought it was was interesting and funny to read in the article:
"...Women have so much trouble admitting they are single [that] they will bring anyone to a wedding," said dating consultant David Wygant. "They hate to answer this question at a wedding: ''Why is a nice girl like you still single?'
"So to avoid the embarrassment, they end up going with a guy they do not like and hoping to hook up with the hot out-of-town friend they met at the rehearsal dinner," Wygant added.
On the flip side, men aren't likely to bring a guest to a wedding unless they are very serious about someone, both out of fear of sending the wrong message to a starry-eyed date and also to make the most of the opportunity..."
I always rather liked Ali MacGraw's answer to a similar question ("What have you been doing this summer?") in the movie Love Story. She shut up that snobby woman in seconds flat with her creative response. :o)
