Joke

When my daughter was about 6, my sister was babysitting for the day. My sister had a soap opera on the tv and during a love scene, my daughter expressed how gross she thought it was that a man and a woman were kissing. My sister explained that when a man and a woman are in love, kissing is not gross. She then said, "Your Mommy and Daddy kiss - they're in love."
My daughter's rebuttal to that was "No they're not - they're married!"
