In my position it makes perfect sense.
Our house is on a lane, mainly used by farm machinery, there is no reason for anyone to come here unless they are visiting someone on the lane. When DH saw their car he knew that the only reason they would have been driving along the road was to come for a confrontation.
DH and I had discussed it beforehand and we had agreed that I would try to call them on Saturday but if they turned up before then we would pay the money as we had calculated it before they got to our doorstep.
I would have liked to have had a rational conversation with the parents about money, preferably when they were not on their way back from the airport with their DCs in the car.
I still don't know what the payment was for, how long, with or without the interest taken into account etc.
The NPDad & my DH were the only people to speak throughout the whole exchange, NPDad was using phrases or sentences that made sense in themselves, but it was a scattering of phrases that made no sense as a whole. As it happens, he made no mention whatsoever of the money. Nor for that matter of the expensive piece of equipment we have of theirs. Having mentioned it to them already, I am not going to approach them to collect the equipment.
I do not have the power to prevent any other childminder or nursery from taking their DCs on. On my childminding FB group I asked for advice on how to deal with the situation, but took care to make no mention of the names of the people, the sex of their DCs, how many DCs they have in total, or where they live.
Their problem finding childcare will be that it's August, some CMs or nurseries are closed or low on staff and every place I know would want to see the DCs before they take them on.
Also, they have just returned from an Amber country which I think may mean that they should be isolating? I'll admit that I could be wrong on this, I haven't read up on it as we aren't planning to go abroad this year.
Too right I'm feeling snippy. If you read the thread and if you have seen the video, I have more than enough to cope with at the moment I have a dying parent, a family getting together who don't get on. I'm not sleeping especially well, I've got a UTI probably because I'm stressed to the max. And now people turning up on my doorstep and threatening me...all for the sake of a princely sum under £150 and me legitimately terminating a contract that they broke.
