Tim: didn't you see? I was talking to that old lady from the back there.

Rob: how old was she,

Tim: i don't know but when I got back to her house her grandchildren were running all over the place so I took her to the basement, put a sock in her mouth and fucked her. After about 10min her grand kids came down and started watching.
