But is it really negative stuff for him to say the tone and urgency of your emails bothered him? Isn’t that more like a correction? Like you might correct your daughter’s behavior but not actually criticize her? “We don’t throw sand in people’s eyes” versus “you are a terrible kid for throwing sand into people’s eyes.”

Negative stuff to me is like “LT, you are x y z,” actual negative characteristics like “you’re very sick” or “pushy” or whatever. He seems more likely to be “LT, I’d really appreciate fewer emails on a holiday weekend” or “I’d like to see you manage your anxiety better.”

Incidentally I don’t see anything wrong with your tone. You stayed polite and respectful.
