can of worms: o que é isso?

Imagine you have a friend who's involved in a very big scandal. She was cheating on her husband and now all the neighborhood is talking about her. While you're talking to one of the neighbor, he brings up that gossip, and you say: Let's not open that can of worms. What does that mean? A can of worms is a very difficult issue you don't want to deal with, let alone talk about it. Literally speaking, a can of worms would be a can full of creeping small little animals in it. Nobody would want that right? Take care!
