Gen Z here. Personally I’m glad to get a call from a close friend any time. Especially when it serves the purpose of them just telling me about something funny or interesting that has happened, to discuss some issue where tone of our speech is an essential part of communication, or to organize some get-together and make plans. In such cases I actually appreciate getting the call and happily pick up the phone. I only don’t if it’s an unknown number, or if the person repeatedly only calls to ask for a favor. Robocalls I don’t get often.

I agree with the argument presented here that one can communicate more effectively by intentionally not making oneself available right away and allowing oneself to be silent first. I totally relate to this in cases where e.g. a friend is asking for advice. However I feel that this is used mostly as an excuse to avoid communication. I don’t think there is a non-negligible proportion of teenagers that really think to themselves “hmm this matter calls for some contemplation, I should answer later”, rather “I really don’t want to deal with this right now”. I also feel that, similarly, what I see in the comments here is less “I don’t answer calls so that I communicate more effectively”, rather “I don’t answer because I don’t want to be bothered with real human interaction”, and I think that’s just sad. How can someone take such pride in intentionally isolating and disconnecting himself?
