I am single and live on the ground floor of a block of flats. Got a knock on the window from a delivery man who wanted me to let him into the block to deliver a very large object. He said there was no response from the flat. I don't know the people who live there. He wanted me to let him in to let him in to deliver to their door. I felt really uncomfortable and refused. I did offer to take a card and put in their box that they tried to deliver. That was refused. There was much muttering from the man on the way back to the van.
Should I let these type of people in? It was obvious he had the parcel but I just feel a bit panicked when people ask to be let in. I feel even more panicked if I ignore then knock on the window altogether. AIBU - now my depression is kicking in to tell me I did this wrong.
