So I am writing what I see people generally do when you stay the night with a friend. Sorry besties, but most of you do this. This also applies to siblings.
1. Play your music even if they don't like it.
2. Ignore them by reading manga, texting, or stay on the computer
3. sing silly songs that make them mad then act surprised when they yell
4. leave the room every 10 minutes.
5. Don't answer their questions
6. take embarrassing pictures of them as they sleep
7. Act like a psychopath for fun and make them scream then laugh.
8. Be random
9. Laugh at weird times.
