Wow that’s a surprisingly aggressive comment. I’ll share why I used to text and call “I’m here”. I’ve had many experiences where the residents had dogs that would absolutely lose their minds and bark non-stop or go crazy when you ring the doorbell. It’s just a better experience when their owner opens the door and there’s a guest. Other times, my friends lived in a multi-unit apartment and I didn’t want to bother 5 other people who I didn’t know. Other times they lived with their family and, again, just didn’t want to talk to them that time. -shrug- but I guess these are examples of not being able to think without a device.

For you, if you’re expecting guests, just tell them to ring your doorbell. Get rid of the ambiguity and give them comfort in knowing the “right” thing to do. You clearly gave it some thought and have strong opinions about it. I’m sure other people are just trying to be considerate in a generation where they mostly grew up living with lots of other people.
