St. Patty's Day woes!

A few weeks ago, Bo came home from pre-school visibly worried.  He brought me his calendar and said, "Mom, on this day (pointing to March 17th) I have to wear green, or else everybody will PUNCH  ME!"
I explained that he might get pinched, not punched, and that seemed to calmed his worries (a little).  However, I noticed that several times over the next couple weeks, he would go into his room and change into something green - just in case.  We are now one week past St. Patrick's Day, and he is still favoring green!  Gotta love that boy!
