I think my Missus is just an awkward git and wants to feel affronted that the woman next door has put a line up without speaking to us.
TBH, it is more or less where I expected to run it, and I had promised the neighbour that we would both agree the line before ANYTHING was done with respect to placing fencing in the ground.
I've looked at it and I think the end panel of my current part-fencing is out by a few inches, and one of our sheds and its base is over the imaginary line.
All these things I plan to correct without a big confrontation or fight, and by mutual agreement. Why make a fuss?
It's 2 wimmins squaring up for a cat-fight, not something I want to get involved in really.
