Well, I think I know from reading this. But I wouldn't know if you were my neighbour would I ?
In fact, I had two deliveries last week that were supposed to come after 6pm, they arrived at 5pm and my neighbour took them in for me. She hasn't complained or winged to me so I'm wondering whether you could be her.
Communicate, that's all I'm saying. I have no idea why you appear to have a problem with this!
