I think CA would agree the death of a family member doesn't fit what he was referencing.Except some of the younger folks will text or email about family news, when i would prefer a personal call. My cousins emailed the death of their mother, (my aunt) in Scottsdale, I informed them when I go I hope my kids have decency of phone call.
With my work, we take numerous requests for research and/or copies of documents. One particular person knows our e-mail address and knows our procedure of doing things, yet she insists on calling to verify if she can make the request and if she e-mailed to us if we'll get it or not.
For us, e-mail is much easier than talking to someone on the phone for a few reasons - we have their contact information and we don't have to worry about trying to decipher and write what they said.
