To tell our neighbour she can't use our garden tap

[minieggfannomore]

The garden of our house (divided into flats) is also divided and our upstairs neighbour owns the bit of garden at the end.

She is a very unpleasant and difficult woman. She didn't actually live here for several years and would not return contact if we ever tried to speak to her about problems (leaks etc.).

She has refused to pay her share for works done (still owes us £500 for damp course and owes girl in top flat money for carpeting the stairs).

Tonight I met her by chance in the street and she told me nice as pie that she wants to spray weedkiller in her garden and needs water for this and could she use our garden tap so she doesn't have to carry watering cans up and down stairs.

I was pretty astounded at the cheek (the last time I spoke to her she put the phone down on me and said I was never to phone her again because I told her there was water dripping through our ceiling and she had to sort it out).

I told her we didn't have a tap she could use. Now I am worried she will do something horrible to us. She is honestly the most horrible person I have ever encountered.

AIBU?

Thanks so much everyone. I am going to buy a tap lock.

A few years ago, when it became obvious she never used her garden (hence waist-high weeds etc.) we asked if she would consider selling it to us. She said no and we said OK no harm in asking.

When she refused to pay her share of the damp course, she ended the conversation by hissing at DH "And I will NEVER sell you my garden".

She truly is the most horrible person I have ever encountered, but as I said the nastiness is so blatant and weird it throws you if you are a normal person.
