No Shoes, No Shirt....

No Shoes, No shirt, no....underwear? My crazy daughter just showed up to lunch without her underwear or pants on...just a shirt....I asked where her underwear were and she said they're in the bathroom...."um, why?" I asked ...."Because I didn't want to get them dirty".......Confusion has set in....Last I checked, you fill a different set of cheeks with your food....no?
