It happens to all of us, sometimes regularly depending on the neighborhood. That is, we hear an unexpected knock on our front door.
The question is, what should we do?
Open the door
NOT the best idea (without doing other things first)… Some people blindly open the door to see who it is or what it is that they want. Don’t ‘automatically’ open the door. Obviously if you know-trust the person on the other side, that’s a different situation.
Look out a window first to see who is knocking
Avoid looking out the door’s window (if it has one), but instead look out from a different or adjacent window – away from the door (they won’t see you that way). If you don’t recognize the person, you could ask through the door who they are and what they want, or you could choose to ignore it completely. The main thing is, it’s best to look first, before blindly opening the door.
