Highschooler skips panties!

Don't know why this has got me so hot tonight as I sit here.
(This is a true recording of a conversation with my daughter)
My 18 yr old daughter mentioned at the dinner table that her "dumb locker-mate" (girl with the locker above hers) told her this morning, "darn, I forgot to wear underwear today!"
My daughter said, "what?"
She replied, "yeah - dumb me forgot my panties today!"
These kids go to an expensive school that requires uniforms.
The girls never wear slacks - they all wear plaid skirts "no more than 6" above their knees." So, not miniskirts - but showing plenty of young thigh!
He locker-mate is a rather voluptuous long haired blonde - always a bit of a flirt, my daughter says. Well breasted - but not chubby. I've seen her in her silky gym short-shorts working out for soccer with my daughter....she's easy on the eyes! Hell, they all are - in those thin loose shorts-shorts.

Now I've had this mental image all evening of this youngster swishing around at school - totally bare-assed under her skirt all day! Air flowing up under the skirt to swirl about her blonde crotch!

Frankly this whole thing is so outrageous that it's hard to believe - no one can forget their panties!
I carefully questioned my daughter. Carefully -- trying hard not to show too much interest (my daughter is VERY aware of all the males showing interest in Ari) ...."you're not making this up, are you? Ariana really said that?!"
"Yes Dad, she announced it - in the crowded hallway before first period, that she had forgotten to put on her panties today! I'm not making this up - and yeah - it makes no sense at all. I've never even come close to forgetting to put on my panties!"
"Yeah - well geez - that's understandable honey!"
"Dad, she was either just feeling slutty today - or she was making the whole thing up - but I was not going to check if she was wearing her usual tiny bikini panties!"
"You often check on her panties?!"
"Dad - we change for soccer practice."
"Yeah. OK honey - time for your homework."
While old Dad rolls this vision around for awhile...!
