My 16 year old knows they have to be out the door by 7:30am to go to school or they’re in trouble with me. The other night they fell asleep on the couch and my 12 year old put on their jacket and back pack like they would for school and woke them up a 7:30pm yelling they were going to be late for school and I would get mad. The 16 year old got up in a panic to get ready for school when they noticed, its dark out. Morale of this story, don’t torture your 12 year old sibling because revenge is sweet.
