It is wild to me that someone hears their doorbell and their instinct is to grab their gun

Seriously, my first instinct (like any normal person’s) when I hear my doorbell is to pause whatever I’m watching or playing, turn off the speakers, and slowly and silently creep towards the door to peek through the peephole and see if whoever rang without scheduling first has already gone away and I can go back to my normal life.

What am I going to do with a gun, shoot the bastard and cause even more people to come to my door‽
