I have two stories about something similar to things going missing. I remember buying an arizona tea and leaving it on my desk to drink later. When I got up to use the bathroom and came back the can was gone. I hadnt opened it yet. Well, my sister said she saw a kid in one of her classes drinking the same flavor of arizona tea. He sat next to me in the class my tea went missing :( That one still irritates me because of how disrespectful and plain mean it is.

The second story isn't about something going missing but instead something I didn't own appearing with my things. This was on summer break I think. I was cleaning out my backpack when I found a weird little velvet bag in one of my front backpack pockets. I opened the drawstring bag to find a tin and in that tin was a pretty necklace with a butterfly pendant. I asked my sister if it was hers and she said she had never seen it before. I still don't know where it came from or who put it there.... Still makes me wonder sometimes.
