We are doing up an old house, having an extension built. Diggers, mud and mess in the backyard. I've met the neighbour a few times and seemed friendly enough. I've noticed her peering over the fence more often, and on chatting, she has bought a set of steps to specifically look over!!!! I thought she was joking, but no. She could equally look far more discretely from an upstairs room. AIBU that this is odd?
