You are asking your child to behave like you did while growing up, without taking into account that your son would be doing things considered rude now. I'm a fully grown adult over the age of 40. I don't answer my door if I'm not expecting someone. They can call from my driveway if they want. I don't answer phone calls in general, and hate talking on the phone. Few have issues with this as they understand that house visits and phone calls is me asking you to stop what you are doing and talk to me, someone who is just going to talk about something minor that can wait if you are busy. Email is just a letter, cold and impersonal, and isn't a way to communicate with friends, though I'll use it from time to time if it is my last resort. I'm sure they'll adapt if smartphones actually went away, but that's not what is going on with your son.
