I've noticed a trend lately that the new one-year-old gets his/her own "smash cake," usually a cupcake, while the main cake is saved for eating. Nothing wrong with that.
As for the 30-year-olds doing this ... sigh. Sooner or later, you realize that you look really stupid in a tutu and tiara. Also, the crazed-looking blonde in the article is from Richmond. On behalf of all of RVA, I'm sorry. :D
