Back in the day, my friend Char called me “Card-la” (better, I guess, than some other nicknames I’ve had) because of my tendency to give and send cards. I’ve toned it down since then, but I still send thank-you notes–more often, according to some of my friends, than is necessary. (My mom was big on manners, OK?) Ah, but this is a good thing, since I’m going to need plenty of excuses to use a stamp. Fellow bus chicks, behold.

It's a bus stamp!

Yes folks, it’s a bus stamp (!)–part of USPS’s Go Green initiative. There are 15 others, which are cool and all, but I’m going to need a book with just the buses, please.
