I decided to work from home today but ended up agreeing to let a colleague use my home office 
He is driving me mad! He thinks he’s being charming but he will not shut up. And some of his behaviour is really weird. Like he keeps trying to use my chair even though there’s another perfectly good one. And a couple of times he’s swiped at the end of the pen I’m using, like he’s trying to catch it or something.
The worst thing is if I don’t respond to him he escalates his behaviour. Right now he’s rolling around on his back in a shaft of sunlight making this weird humming noise. It’s basically impossible to ignore!
The absolute worst thing is he came in and out of the room about 8 times in a row then sat on my lap and licked my face. Gross - I don’t want to think about where else that tongue has been.
WIBU to ignore his protests and shut him out of my office?
