For me, it's remembering names, not a great weakness in a teacher. I have a wonderful kid in 7th grade, Adam. He is very nice, smart, generous, and helpful. His older brother, Dan, not so much so. Dan was my student a couple years ago, guess what name I keep calling Adam? You should see his momentary scowl when I do so, then he laughs. I really like Adam! He has a wicked sense of humor though, he seems to intuit my antipathy for the art teacher, so he'll say, "That's ok, Ms. XXX it happens to everyone."
