The most disgusting thing my daughter ever did was when she was 2. I was holding her while standing at the counter at a McDonalds. There was a long line of people behind me. For no apparent reason, she puked massive amounts of vomit into my hair, and down the back of my shirt. I walked out the door with her, without getting the food I ordered, and without asking for my money back, with angry and disgusted stares from the crowd.
