Oh I can definitely relate to this. There's a great scene in the movie Moneyball where one of the leads is negotiating to hire someone. In the middle of the conversation the lead hangs up. Stunned bystander says "why'd you hang up? He was still talking!" Lead says "He said yes." That was my old boss's favorite way to explain to his eager PMs that once you give the answer that's requested, shut up. Everything else is superfluous at best.
