St. Patrick's Day

Calvin: Mom, when is St. Patrick's Day?
Me: In like a month.
Calvin: Oh, good I can't wait! That's when I get real gold!
Me: (panicked) Real gold?! I just don't remember that tradition.

Calvin then shows, me a gold coin from preschool (totally plastic) and the gold painted rocks he dug up from my mom's sandbox (Jill genius plan). He is saving them to sell for money one day.
