My 2E second grader told me that she has already learned to "dumb it down" in school. "Mom it's just not a good idea to use words or talk about things that the other kids don't understand." I told her she doesn't need to do that - kids can ask questions if they don't understand what she's saying. She looked at me like my little choo choo had gone chugging around the bend...

Sadly I think she may have decided on a good course of action...
