I loaned my iPad to my boyfriend (now an ex boyfriend) in an airport. I had to go pee and he wanted to check his web-mail. So I gave him my baby and we were to meet in the coffee shop. When I got there he was checking his mail and eating a glazed donut. Needless to say baby's screen was covered with sticky surgery doughnut goo.
I was fereous, took it away from him and cleaned it up, first with a damp kleenex, then with my mystic maid personal cleaning cloth. He's lucky the company had made separate hotel reservations for us because he wasn't allowed in my room on that trip.
