I Pranked My Brother's Alarm Clock

I set my brother’s alarm clock an hour ahead one night. Just for a laugh, you know? He woke up early and rushed to school, thinking he was going to be late. When I told him later that it was just me playing a prank on him, he looked so disappointed. But also kind of relieved when he realized how close he came to being really late. It made me feel bad for a second, but mostly amused.
