I probably am BU here but I am totally fed up with my neighbour.
We live in a flat and share a communal garden and store my DC toy car down the ally way out of the way and DC plays on it regularly when we go outside at home.
Downstairs neighbour had visitors and let there DC play on it. This isn't the first time this has happend and I have found the car else where not where we store it DC saw out the window and got very upset that another child was playing on it.
Now I dont normally mind but I dont really speak to her and she knew it belonged to us yet she didn't come and knock on my door to ask me or DC whether it was ok.
I went and took the car an put it out the way.
