Neighbours can be such an unthinking pain in the you know what!!
I have recently had to spend a time and money to fix a really crap bit of work by my next door neighbour. Considering he is a qualified tradesman, who has worked in the building trade all his life, I really would have expected a better, neater job.
You could always see through the hedge between us, which wasn't a issue until they built an extension with great big bloody windows pointing straight at the boundary hedge. Then a week or so ago, he removed a Berberis plant that was part of the hedge and put up a bit more trellis and this really crap green stuff that looks like green tinsel to block the hole he had created in the hedge. Incidentally, notice the top piece of trellis in one of the pictures. I had to make enough of this to go all round the garden to stop Tilly jumping the fences when she was younger, and the part he put up is identical to a piece that went missing a few years ago. That in itself is interesting! When putting up the trellis, he initially put the wooden struts to support it on our side of the fence! I had to ask him to move them, which really shouldn't have been necessary either.
