Spider relaxing?

This was about as spooky as it got for me today! This is my friend Boris - he's a spider who lives on my window at work. He arrived a couple of days ago, along with a couple of other spun cocoons, but he's the only one that's been out to play.

He's about 0.5cm, so not very big and scary and to be honest has spent most of the day like this with a couple of his legs sticking out. may be he'll be out tonight scaring everything in sight? Somehow I doubt it!
