Got a note from my seven year old's second grade teacher. She took a day off and the sub told her that Billy refused to stop talking and would not do his work. His regular teacher talked to him as it is becoming a big problem in class. She moved him to an area by himself. When picking up her class from art, the art teacher informed her that Billy would not stop talking and didn't do his assignment correctly because he was talking through the directions. He asked Billy multiple times to stop talking, but he continued. His aunt told me he talks incessantly about poop and other gross bodily functions, about a teacher's big butt. I have told him about gross talk and he doesn't do it here, so I thought he was cured. Apparently not! What to do, what to do?
