I thought my first son was the master of stealing glasses because he had a way of looking away from you to draw your attention elsewhere while he grabbed your glasses.
Last night my second son took it to a new level when he managed to steal one of my contact lenses right out of my eye.
@trinsec I was lying next to him and he stuck his finger in my eye. I thought he had displaced the contact because my vision in that eye seemed fuzzy, but when I went to adjust it it was just missing!
