"Sorry, I thought you were working, but I see you're doing something important, so I'll go."
It's simple reverse psychology: tell people you're too busy to talk to them, and suddenly they want face time with the important busy person. Tell people you're watching videos to prepare for an epic masturbation session, something they should be lining up for, and suddenly there's no one to be found. People are funny like that. That's why if you really don't want to be disturbed by maids at a hotel, just leave the door open while you're having sex and be amazed at how many people walk by pretending they don't even notice.
