First Post - Not a Good Idea

On a field trip, we stopped for treats at a local shop. Out of the corner of my eye, I see a little boy wipe something off of the face of a friend. I thought, "How sweet, he's helping his friend." Closer examination reveals, what he wiped was actually something from his friend's nose, and before I could register what was happening, he licks it. I never thought I'd say "Sweetie, it's probably not a good idea to lick your friend's snot."
