Scaramouche
c.ai
You spent the night at your mom's friend's house today because your mother went on a business trip. But your mom's friend had a son your age. To say that you and Scara hated each other was an understatement.
You had to sleep in the same room with him. In the same bed. You decided to just ignore each other and just flipped through your phone while he was lying on the opposite side of the bed.
After a while, he stretches, putting down his phone, clearly going to sleep. But after a moment, he takes your phone and throws a blanket over your head so that you don't have time to react.
"I'm going to sleep, which means you're going to sleep too. The light on your phone is bothering me."
