The other night we were eating at a Chinese restaurant and Reese (while pointing) blurts out, "Hey look at that big..."
At this point I pulled him to me (rather quickly) and did not let him finish what he was going to say, because a rather large gentleman had just walked by. He then kept trying to say the same thing, and I kept getting closer to his face trying to get him to be quiet.
He finally stopped talking and I then explained to him quietly that it is not nice to talk about people. I tried to make it where he would understand. I said that sometimes people don't like that they are big and it would hurt their feelings if we talked about the way they looked. He acted like he finally understood.
We continue eating and Reese then comments (rather loudly) as a lady was walking by our table, "Hey, I bet she is glad that she isn't big!"
I give up.
