I forget how this tradition started in high school but I remember vividly being in Target with friends and picking out ridiculous kid cards. The idea is that all the numbers have to add up to their age (i.e. 6th birthday card plus 10th birthday card means you are 16). As we have gotten older, the cards have gotten more ridiculous. It is so much fun getting 5 funny cards than one because everyone knows more it better (at least according to the little kids on the AT & T commercials). This is my recent stash of cards. It’s always funny to be standing in Target for like 20 minutes trying to do simple addition as you add up the cards and trying to make the numbers work!
