Had some 6th graders in my room after a situation with a friend of theirs. (They act like their friend was dying or something, but the friend was fine.) Some of them saw my CPR poster and commented on how gross it has to be to kiss someone and such and then asked me how I felt about it. I told them, "Eh." and shrugged and then one of them said, "But that's sharing genes and stuff!!" I laughed and said, "Well that's why they call it the kiss of life." And they all laughed and said gross.
6th graders crack me up sometimes with their way they process things.
