"I appreciate you" - when did this start?

The hi/pretty good thing sounds very odd. If I overheard that, I would think it went like this:" high?"
" Pretty good!" (this Maui wowie is terrific shit).

Why would your choir teacher say “I can’t hear” when he means, “none of you can listen, you’re talking too much/too loudly”?

My bugaboo is “I feel ya.” NO, you don’t, ace. Back off and go away.

How about, “Wow, are you stealthy. I didn’t even notice.” And then walk away.

I got over the “uh huh” thing when I realized people were repeating what they said to me…

Them - “Thanks for shopping at Macy’s”.
Me - “Uh huh”
Them - “Thanks for shopping at Macy’s”
Me - ???

After having a variant of the above conversation several times a day, I realized everyone thought must be hard of hearing and saying “huh?”

I trained myself to say “Thanks” or “You’re welcome” pretty quickly after that.

I learned “well, bless your (his/her/their) heart” years ago, and I’ve never used it in a genuinely well meaning way. It usually means, “well aren’t you stupid, but I suppose you meant well.” I’ll also say “bless his/her heart” when I hear kids screaming their bloody heads off and the parents aren’t doing anything about it.

A standard one here is “Listen, thanks a mill!”

A part of the “Uh huh” type responses to thanking may be born out of the excessive, employer-enforced thanking. I try not to do it, but it comes out sometimes when I’m being thanked for something that was not, in fact, a personal favor to the speaker or even slight inconvenience to myself. (Like at the grocery store. I got my food, you got your money. We’re square.) When it’s genuine, that “You’re Welcome” just comes out naturally, but when it’s fake/used a rote greeting, I tend to stumble (Or respond with “Have a nice day,” or something else more appropriate for the actual situation.

geez, some people. What’s wrong with “much obliged”?
