AGREED

I think expecting an immediate reply goes hand in hand with the sense of entitlement which is becoming more and more prevalent.

There are times when I feel it absolutely unacceptable to be using one's phone. Work and school are obvious examples. No you don't need to be available while there. People can leave a message. If it is an emergency the message can be transmitted to you by the employer or school office. It's what we did in the old days. I feel too that using one's phone at all is an intrusion. When I am socialising with a person I expect their attention to be on me not their phone. Nothing riles me more than to be trying to talk to someone and they constantly interrupt my time with them in order to use their phone. Having dinner with me? You bloody well better not take out your phone!

As I said before, your phone is not the priority. To expect someone to make it so is being rude and self-centered. Again, want an immediate response, use the call feature - that is what the phone is for.
