Back in college a younger sister of a gal came to a party. She got way too drunk and was coming onto all the older guys (including me). She was a real cutie too. She ended up passing out, and we locked her in a bedroom with her older sister to take care of her and me and a buddy guarded the door as the other guys were trying to get to her.
Yeah - we were stupid college kids. But luckily not as stupid as some/most.
This is what gentlemen do: protect women.
Not stupid at all. You had/have a conscience and you were brought up to tell the difference between right and wrong.
