Please explain what goes through a teenager's mind!

We had about 4-6" of snow yesterday morning, but the kids still had school after a 2 hour delay. What does my 15 year old daughter wear to school? A mini (very mini) skirt, no stockings or tights, and a pair of tennis shoes! Does she think its spring?

I'll tell you why she did this - she was in a soccer game Sunday and someone dove their cleats into her and caused a bruise on her whole thigh - nice and green, blue, purple & red! She wanted to show it off to everybody!

Bruise or no bruise - she should have enough common sense to wear pants - or at the very least winter weight nylons! She had opportunity to show it off at gym or during soccer practice with her school team!

So, all of you teens on here - would you do the same thng?
All of you parents with teens - would you roll your eyes like I did?
And somehwere along the line, would someone kindly explain the teenage mentality?
