This is going to come across petty, but
i have an outdoor tap on the side of my outbuilding that is opposite the back of my house. It comes out of the ground and I solve checked with the neighbour on my other side to confirm it was definitely my tap as he’s been there since year dot. The neighbour’s have a small shed that is attached to my outbuilding on the side where the tap is (We are a row of terraces) and they moved in a few months back. I’m not on a water meter, however, I think they have been using my outdoor tap to water their plants (they have quite a few and are growing something in one of those zip up green houses)
And I think the neighbour on the other side of them has been feeding the plants for them while they’ve been on holiday… so I think the neighbour 2 doors down has been using it as well!! I only know this as the tap is turned in the other direction I left it in. I’m out of the house 8.30- 5.30pm, so have no idea when it’s getting used
I told myself I’d wait until I saw them using it, but if they’re using it while I’m at work, how am I to know?! Am I being ridiculous?
