Asked in Siblings
How are you supposed to babysit a sibling that does not lissen and tells you that your not the boss of him?
Find his weak spot. For example I'd tell him that I'm going to ring mum right now and she'll REALLY have it in for him. Maybe try (if they're older) that you're going to go making up embarassing stories about them and telling their girlfriend. If you have to be mean, then do be mean. It's the only way to get through to them sometimes! Hope i helped!
