Mine do this too. If I'm sitting on the couch watching TV and get up to go to the bathroom, I come back and there's one (have five) laying where I was sitting. If I'm on the patio and go inside for a cool drink, I come back, there's one or two in my chair. There are seven other chairs on the patio that they could sit in, but, no, it must be the one I was in! I'm not sure if it's a "look at me, pet me" thing or what.
