Your feedback is wonderful. Plus I know I’m not alone in this problem. Keep it coming. We need each other.
I have found that if one is very, very tactful and uses the correct tone and approved lingo, one can get away with saying quite a lot. For instance, use "communication" when talking about language and say "I'm worried about communication with some of my co-workers... I'd be so upset if I misunderstood something important because I didn't catch what they said." That sort of thing.
