Who'd have 'em?

I don't do much on most saturdays: a load of washing, a few dishes (or a lot) a bit of shopping maybe and a coffee out somewhere.
Today was different.
Early this morning I was on my way out and Millie slipped past me, through the gate and down the street...
by the time i found her she had "viciously mauled" a tiny dog. The owner was screaming hysterically about the two drops of blood on her dog's chin and a by passer had stopped to save the day.

Anyways....I apologised: profusely, seriously, grovellingly. I thanked the by passer. I offered to pay the vet bill. I apologised again. More. Sincerely.
Then the owner accused me of standing and watching as she was attacked. The by passer left. I gave my address and phone number and asked to see her little dog. She declined and rushed to the vet.
An hour later I phoned to ask about the dog. There was no reply and none an hour after that. Eventually a text came. The dog was "clinically ok" but the vet had treated the owner for dog bites. Interesting. Do vets treat people? I didn't see any bites. I'm sorry, I said. Send me the bill. The bill didn't come but she wanted to know if Millie is vaccinated. Yep, she is. Then came the promise to call the council about the uncontrolled dog. Eventually a corrupted file came. I asked to have it sent again. Tomorrow she said. Then came the message saying the dog (the clinically ok dog) might need to go to the vets again and the vet didn't shave the dog because the dog didn't allow it.
I'm starting to feel like she's enjoying this, sending veiled threats about her completely unhurt dog and her own injuries which were not immediately visible or treated in a medical facility.
This is a drama I don't need. Do you think the invoice will ever come?
