When I did it, for some reason they used to talk to me like I was a child, rather than a mid forties woman.
"Hi, how's u?" (The usual opener in my area)
Me: "Hi, I'm good thanks. Hope you're well too"
"Aw, thats good. So what has a lovely girl like you been up to today?"
(after I got a version of this a few times, I used to become mildly sardonic and reply with something like
"Oh, busy day at work, with a no less than three (3!) dissections carried out plus a partial. Once I got home, I then went out and ran 22 miles in preparation for my next Ironman".
Them; "Aw, thats good. So you like to keep busy then?"
I once got "You do have a busy little life don't you!"
