I would hope that her teacher checking out your ass 15 years ago would be weird, Den Den - You were like a whole 3 years of age back then. Which would make you way too young for her teacher and just a bit too old to be a saught after as a groupie for the Lost Prophet's lead singer (too soon?)
Many females tend to remember moments as such when they feel uncomfortable by the situation. Much like an uncomfortable moment where you catch a cousin of yours checking you out or something. The difference is that as a man you have the ability to bury it deep down to the point that you eventually block out that moment from your mind; something that females are not able to do as they remember virtually every fault to have occurred in your relationship and often remind you of them.
But old men are great for a solid rant and sporadic actions from time to time... Prime example being Wade heading to Japan for the New Year.
