To celebrate my kids both having their wisdom teeth removed this morning, I'll share a "story" from my childhood.
My brother had his wisdom teeth removed when he was in high school. After the removal (which I won't call a surgery since our dentist did it, with Novocaine and nitrous oxide for anesthesia), David was recuperating at home.
He was walking down the hall and he fell to the floor. I was standing nearby, and saw him fall over. I stood their dumbfounded while he moaned. From another room, my mom asked what the noise was.
Staring at my brother prone on the floor, I answered, "I think David fell down." In retrospect, I am pretty certain that he had fallen, since I watched it happen. But apparently I wasn't confident then, so I conditioned my response with "I think...".
Kids are weird. Or, I am weird. Not sure which is relevant in this case.
