I've been told the same but I know I've also not been at times; that's just me being human I guess. As for the glaze, tuning out or listening to respond, I agree with you that it's easy to spot. Stopping mid sentence is a good method, probably much better than the open handed slap to the head I usually deliver. (Just kidding of course...or am I?)
Thank you for notifying me you'd received the notifications notifying you that I'd noted your content and acted accordingly. It's notifications like yours that notify me that my noticing your content is indeed worth my notice and I look forward to more notifications coming your way based on my noticing of your content.
I think that means, you're welcome. Lol.
Eh, um, I agree entirely... I think.
