I have to admit, I did some pretty stupid things as part of group of teens.
Example: In Houston for a track meet, we all started a water balloon fight around the motel. We were hiding around the bushes by the pool, trying to ambush each other. Stalking each other from the second floor railings of the motel. That sort of thing. Not an all out loud noisy affair where other guests would be accidentally caught up in it, and we certainly thought we were being considerate by watching out for others. I had the perfect water balloon and was saving it for the captain of the boys team, my crush at the time. I looked over the edge of the railing and there he was! Standing just underneath my position, casually talking to someone that I couldn't see. This was my chance! I dropped the balloon over the side. It landed right on his feet, and splashed the police officer he was talking with. ::sigh::
We were all restricted to our rooms for the rest of the meet.
The locking arms could be dangerous, but otherwise I'm more likely to give them considerable latitude.
