My daughter keeps calling me cute names: Swiper, Papa Bear, and other fun characters from shows she likes. What an imagination!
One of my favorite names though is not even intentional. She keeps starting to call me Mommy, then remembers that she's talking to me and changes halfway through to Daddy. The result sounds like 'Mahdi'. I could interpret myself as the Twelfth Imam, but I prefer to think of myself as the Savior of Arrakis :)
