Painting The Shed
Telling your roommate you're about to have sex and hoping they'll just leave without asking questions or making a big deal out of it.
I told my roommate I was painting the shed and he just said, 'Okay, I'll be in the kitchen.'
She said she was painting the shed and I left before I got hit with a pillow.
He yelled 'I'm painting the shed!' and I ran out like I was on fire.
