For some reason, when I was little I used to think that if they were flowers in a store it meant it was someone's birthday. I could never figure out who, so I would just pick off one of the flowers, go up to some random person and go "Happy Birthday!!" No one ever refused the flower, but I imagine most of them thought it was pretty weird!
