My least favorite words are: “Oh, by the way.”
Whenever someone says that, it means they forgot to tell me something important, and they’re about to make it my fault for not knowing about it.
“Why didn’t you tell me?” is not the proper response to an “Oh, by the way.”
Instead, you should say “I’d like you to put your oversight in writing so that I can hold you legally responsible for any consequences that result from your failure to keep me informed.”
They never do.
This is why I record everything…
Oh, by the way, I’m recording this.
