Me and a friend spent a night during our lower teens scaring an elderly couple. Then they came out of their house and we ran into a forest nearby.

By the time we came back, they had taken our bikes inside their house, and we had to go apologize to them and ask for them back. They called my friend's dad who came and scolded us, saying one of them could've had a heart attack and died. Guess if I felt guilty and stupid afterwards. Served us right though
