I found that in recent antisocial times, more and more people elect to ignore doorbells and not even check the door unless they specifically know someone they expected is there. They just act like nobody is home
To be fair, the vast majority of the time someone is at my door that I'm not expecting, they're trying to sell me shit I don't care about. I do not answer my door.
one of the perks of living in an apartment, the outer door is locked so if someone's knocking on my door it all but has to be the neighbours and they're not gonna bother me for no reason.
Maybe some people have this weird technology where they put things in or over their ears to hear only what's in the device they're texting through and can't hear any outside noises.
