Or so it seems...I just had a class where we discussed a video on ancient Rome. One of the students was telling me which fact was the most interesting to her and I didn't hear her. So I asked again, and she laughed and said "Yea, that's what I just said..." several other kids laughed along. They do it often, laugh and giggle when I don't get someone and have to ask again... It bothers me. I'm trying to just let it go, and I'm better at it, but it's hard. How do you deal with this?
