I live on the top floor of a block flats. 2 flats per floor. Rented from a Housing Association. Diagram not to scale
The squares in the corner of the flats are our front doors. Next to our front doors we each get a space, probably the size of an understairs cupboard. The HAs contract with us says this space is for the storage of pushchairs (which I do for DD) and non perishable food and drink items. The alcoves don't have doors on so you can see into each others alcoves and easily access them. We're not allowed to add doors or even poles for curtains/screens - I've asked before, but the HA say the block is secure so anything that gets stolen should be easily found.
Over Christmas I stored some of DDs Christmas Presents and some alcohol there. I left some of the chocolate out there along with some bottles of beer.
Neighbour has a dog. On Christmas Day after coming back from family his dog was off lead and while neighbour unlocked the door, the dog got into my alcove, where he promptly knocked over a crate of beer bottles licked that up and ate some of the chocolate.
This morning neighbour knocks on my door and asks me and DH to pay for the vets bill he's now got as his dog has become very ill from eating and drinking the contents of my alcove.
While I sympathise because it's awful when your pets ill I have a cat and I hate it when she's ill I feel it's the neighbours fault for allowing his dog to be off lead in the communal areas where he may have access to stuff he shouldn't be having such as chocolate.
Neighbour is coming back later to discuss it and I want to know if I'm UR to refuse (we can't really afford vets bills, we have pet insurance for the cat for this very scenario)?
