I'm relearning Patience. Which I never mastered in the first place.

You know who has a lot of Patience? The doctor.

Edit:Remember, it isn't Patience = Virtue. It's Patience is an element of Virtue.

Edit 2:As was pointed out to me, besides having a Happy Mothers Day, also have a Happy Pythagorean Triple Day!
