Another Question!

I know this is my third question, but I'm just curious. Okay, so last night as some of Du may know I heard knocking and rattling. I didn't tell Du guys this but, I heard a maus and yelled out to ask who was there. The maus suddenly stopped and Du could only hear the door knob again... Was it Peter? Also! If Peter never went to never land, how old do Du think he would be?
