My newest DIL is a pre-K teacher. In my opinion she is a real life super hero. Have you ever met someone who was doing exactly what they should be doing? That's her. She gives her students her all. She seriously loves each and everyone of them and glows when she repeats little stories about them - or as she calls them - "her babies". I really admire and love her for loving them.
Anyway, for Christmas I made her a t-shirt that reads "I Teach Pre-K. What's Your Superpower?"
