I am the one who knocks. Unless there's a doorbell. Who doesn't enjoy an easy doorbell? If the homeowner has a working doorbell, then they're signaling that's how they'd like to be alerted to a visitor. Using the doorbell is respecting their wishes. Why do people circumvent the doorbell and go right to punching the door in its face? Why do that? That should be a last resort. Be a good guest and use the doorbell. Though, other people have touched the doorbell. Other fingers. Germ-coated fingers. Dirty dirty pandemic fingers. Nasty fingertips that have been places you don't even want to know. A mob's worth of filth concentrated on one single focal button. And sometimes, if there's a dog, that doorbell could set off an explosion of barks. An aural assault. That aggression can make you feel guilty. Like you did something wrong. Like you're an intruder. Like maybe the police should be involved. Like maybe you should get a lawyer. Get lawyered up. Sometimes it's better to just text.
I've also experienced a conversion and have flipped all my Suntups slipcase spine out.
