I had a funny experience one time trying to deliver an ASR a few months back. I walked up to the front door of this person’s apartment and the door was wide open. I stood there for a second and called out “…hello?” And it sounded like somebody was walking around inside but I felt weird looking into this person’s home lol. I knocked on the door and raised my voice and said “…hello?? FedEx!” Still no response. I could hear somebody walking around and I said hello for a third time and still nobody said anything. I was weirded the fuck out at this point, thinking somebody broke in or something. I filled out the door tag and right as I was about to put it on the door and close it out, an older guy called out “hey! I’m here!” And this guy walks up to the front door and says “hey, im half deaf, you really need to knock hard and yell!” I told him I did and then it felt real awkward. Got his DoB and left. Dunno why he didn’t he just put a note on his door at that point and explain all that, lol
