The biggest things I struggle with in my family is the older folks not seeing SMS as asynchronous communication. Just because I’ve had time to send a text, it doesn’t mean I’m free for a call, and it doesn’t mean that I’m going to be able to hold an ongoing conversation right this second.
At the risk of sounding misanthropic, I struggle with phone calls in general and find them to be a terrible distraction; not just for me but also for whoever I happen to be with at the time, as a shared activity means we both have to stop what we’re doing.
Sure I could just ignore the call, but at this point there are several members of my family who are at the age where an unprompted phone call could well be bad news. Then when I turns out to be for idle chit-chat in the middle of my work day I just end up feeling both irritated and guilty for feeling irritated.
