Eh, I actually have a little story to tell regarding this if you're bored. Happened just a few days ago. Not that special but whatever.
Just the other someone ringed my doorbell at 8 o'clock in the morning. I had already somewhat woken up but was still lying on the bed. I went to the door and it was the neighbor lady and it was pretty clear she was in distress. I was in my underwear and had a huge morning boner but I opened the door anyway and kind of tried to hide the boner with my hands and such. Anyway, she had apparently had a heart attack or something like that and had called an ambulance. They had recommended for someone else to come to open the front door (I live in an apartment building) so she asked if I could do it. My mind was still pretty hazy from the sleeping and it took me a bit to understand her request - unfortunately didn't figure out to ask her if she's ok or if she'd like to come inside while waiting for the ambulance or anything, like a decent human being might do - and then she went back inside her apartment.
I got ready to go the front door but I couldn't find my keys from anywhere though normally I leave them on the table. I eventually found them but then I notice from the window that the ambulance had just come to the door. I hurry downstairs but fortunately some resident had just come from outside and let the ambulance man inside. He apparently wasn't in that big of a hurry anyway.
I waited for the ambulance to leave before leaving to work and fortunately didn't see her being taken to the ambulance at least so I guess she didn't die or anything. Would've gone to check up on her but it's not always so easy as a socially anxious shy introvert. I hope she's ok.

Anyway, other than that, I do usually open the door to people. Even if it's clearly JWs or something like that. I've debated with JWs a couple of times too. They practice their answers well though so it's hard to get around their bullshit, but I looked up their most typical answers and felt like I did manage to get through the bullshit at least a little and might've got them to actually think about it genuinely even for just a little bit. Not that it's gonna make them atheists or anything, but change can happen slowly. Some of their ideologies really are fucking nasty.
