I’ve been visiting my sister and her family this week, and my ears have been tickled often with the most beautiful sound—the uninhibited laughter of my eight-year-old niece. It’s genuine and funny and contagious.

Laughter is often infectious (good infection, not pandemic infection). How often have you heard laughter, didn’t know the source, but it made you want to laugh too? You laugh along, and before long you’re just laughing because if feels so good.
