My neighbour (who has SN) keeps putting flowers through my letterbox. I am pretty sure it's the neighbour because of the type of flower ie it is the one that grows in his garden. Also, the neighbour knocks on the window repeatedly when I'm in the garden hanging the washing out.
I am currently just ignoring it all, but I am slightly uneasy. The neighbour has some kind of fairly severe SN, appears to live with at least one carer and have others visit. if we pass in the street I sort of nod and smile, and once or twice they have taken parcels in for me (and once one of the carers knocked on the door to ask if the pair of trousers the neighbour had flung over the fence into our garden could be returned).
I don't think he's at all dangerous, but is there anything I could/should be doing?
