A Day for Wishes and Tricks

It’s St. Patrick’s Day, that Irish holiday when we wear green clothes, eat green food, and maybe score some “luck of the Irish” for ourselves. There are leprechauns, those funny elf-like fellows from Irish fairy tales who are only as tall as kids, but have big magical powers. Supposedly they keep all their coins in a pot of gold at the end of a rainbow, which would be a great thing to find. It’s even better to find the leprechaun himself, because if you capture him he’ll grant you 3 wishes. Another Irish symbol is the shamrock, or 3-leaf clover, because long ago people in Ireland believed that carrying a clover kept you safe from evil spirits. It’s still a sign of good luck today, and 4-leaf clovers are even better luck. Who knows, maybe today you’ll find a leprechaun or a clover – or at the least, you’ll get to eat a green pretzel.
