This very same thing happened to me during my brothers graduation in 97. My sister and I got up to take pics of him graduating. We came back to our seats where my whole family was sitting mind you, to find my purse had been stolen while I was taking pictures. It was sitting right next to my husband and they still got it. I was so very upset, but didn't want to ruin my brothers graduation at the same time. So I didn't tell him about what had happened for a few days. It's just shameful.
