AAAAAARRRRRRGGGGGHHHH! Why do they do this? Puppy, coach, anyone else help me with what might have happened here?

Damn woman just turned up unannounced at my door. First time she's bothered to come to this side of town. She stood at door holding cheque book. Convo as follows:

"I couldn't find you house, the door is off the wrong street"
"Yeah, it's a bit odd isn't it"
"I've come to pay you for this" *waves court order at me*
"I see, why don't you come in then"
"I don't know what we have to do with it, I think I need a reciept"
"I'll write you one. How is the new job then?"
"I only started this week. I'm in an office full of mentally unstable people"
"You'll fit in well then" *with a smirk*
"And I don't know how long I can last the commute. How is yours? Are you in a new one?"
"I'm doing surgery, it's fine thanks."
"Is that still with children?"
"Yep, paeds surgery"
*exchange of chq/reciept*
"Can't you make it legible?"
"You know me, always had doctors handwriting"
"Yeah you do"

Then I showed her the door. She said something like "see you again sometime" and I said "Bye."

She looked rough. Not at all like someone who is thrilled to have just had a lovely holiday with her OM in Italy.

Why did she show up here? Why didn't she just post it? Why was she here without my remaining post and belongings which she seems to find irritating to have in her house? No DVDs returned. It is about a 1hr 10 min drive from hers to here and back. She has no reason I can think of to be on this side of town. She never came to this area once in all the time I've known her (despite it being rather lovely).

Maybe she heard I had a date last night (which I did, and was just as planned, a chat over dinner with a potential friend)?

I'm feeling quite odd.

Reality is that which, if you don't believe in it, doesn't go away.
