Purr Purr, Yikes! Thump

Last night I was laying at the foot of the bed on Monika's side when she came in and laid across the bed to give me pets. I was enjoying her attentions, so I rolled onto my side so she could pet me more. Then she started petting my chest, so I rolled onto my back so that she could give me belly rubs. Only one problem. I forgot I was in the corner at the foot of the bed and I rolled right off onto the floor. I'm so embarrassed!
