We have some neighbours a few doors down that took to sneaking around in the (enclosed) front garden and taking discarded cigarette butts from the designated pot we have out there for them.
Two of these plant pots went missing over the course of a year or so. It finally clicked who had stolen them the last time it happened so I put a note through the letterbox asking them to please return the plant pot. The male of the pair came and knocked on, returning the plant pot and that was the end of that.
Fast forward to last night DH arrived home at about 10pm and as he came up the path he saw one of the pair at the plant pot.. again.
Tired of them sneaking about in our garden he told him in no uncertain terms to get the "F" off his property and stop creeping about near the house late at night, he has kids in here etc.
Do you think he was being unreasonable to lose his temper? I will admit I do feel a bit unnerved about strange men creeping about in the garden, it doesn't sit well with me, however supposedly harmless his intentions were.
