I have a right of way across the neighbour's garden to the gate, which leads to the access alley.
When neighbour goes out, she leaves the gate swinging in the wind, and it bangs away all day. At the weekend, DP got fed up and went through her garden to shut gate. I've just done the same today, but have been seized by a hideous qualm!
AIBU to shut her gate?
(Not sure if it makes any difference, but she's a tenant and the banging is knocking the screws out of the catch.)
