What came out of her nose!?!?

Yeah, blowing a body part out of your nose sounds VERY strange and very unlikely. She probably had a good bit of pollen and dust from being outside along with mucus trying to clean her nostrils and sinus. So what you most likely sent home to her mom was an aculation of...boogers...yes indeed! Very impressive ones at that! Tell the child to drink more water, maybe useKleenexaline spray to help cleanse her nostrils and use Kleanex. You're a great supervisor, though, and I'd want you looking after my kids if you worry about them like you do; shows you have a good heart. Godloveya.
