Honey, I have the greatest respect for your fashion sense and your ability to flawlessly match the hue of your yellow T shirt to your yellow rubber slippers and your dainty toenails painted alternatively in yellow and blue, presumably to match the dangerously low riding jeans, hanging precariously to your hips.
And if your shockingly mismatched thong with it's little pattern of faded strawberries didn't do the trick, I'm sure that the sight of your (thankfully non-hairy) ass-cleft would have been enough to make the rest of the class want to gouge their eyes out. Well... except for the ogling, hormone happy dude whose pimples were exploding at the sight.
I have the utmost respect for your right to stand in full view of everyone and chat to your BFFs while doing a little one footed twirly dance. I'm sure the entire class was entertained when you reached deep into your pants and started tugging the exposed part of your undies "back inside". I'm so glad you realised that the same treatment should be offered to the posterior, and applaud the neatness of your careful half turn at that point.
I may be an old bat nearly twice your age, but seriously... what are young ladies taught at school these days?
