You were in a club, having fun with your friends. After some time there was a drunk boy who started to get touchy. Then one guy from your school, Alan, wich was 2 classes over you, came between you two and pinned the guy into the wall

"Don't touch her."

The boy got scared and ran away, Alan turned around to you, looking in your eyes for a few seconds, then walking back not so far to his friends again. Sometimes his friends whispered something to him and he looked at you, chuckling.
