My god...

I went in my parent's basement in search of 2 boxes of long pile fur I had.. It also kept all my boxes from my last move... Whiiiich my parents precariously stacked around the room touching the roof.. Geez. I was doing a decent job climbing and searching until I saw a snake skin. I pussied out after that >.< maybe I'll find it when I go through the boxes and throw crap away. Why is it snakes skins scare me far more than the actual snake...?
FA+

A skin is a suggestions that somewhere, there may be a snake and it may bite your ass :3 But then again, it may have already died or left. Or maybe it's behind the next box, ready to strike.
Or maybe that was a skin that you or your parents collected in the past, in which case my theory has no sense xD
And it does sound dangerous, digging through a mountain of boxes, with a potential snake on the loose O.o Still, if there aren't any rats or mice in the basement, it wouldn't have any food, so I wouldn't worry about it ^^
