Bless her heart...
I am originally from Nebraska but have been in Texas since 1985 and I don’t have much of any accent. But I do have to talk on the phone frequently with people on the east coast. On those occasions I really lay on the Texan accent on purpose and pepper it with lots of “Yes ma’am” and “You betcha” responses. Makes my day. Have also on occasion said, “Well, bless your heart and thank you so much for the info.”
LOL! And that has several meanings where I’m from. But I know whatcha mean. ;-)
LOL, I am from Mississippi, have a nice day y’all.
LOL. A perfectly genteel response.
