When i was little, I asked my mom if we could get the pretty stamps at the post office instead of the plain flag ones. She told me "No, they're more expensive." When I was in college I went to buy stamps and decided to splurge and get the pretty ones and so I asked the post office person how much they were. I went home and told my mom and I don't think I've ever seen her laugh so hard. Now i get the expensive stamps all the time.
