Personally, I think if anyone takes the time to acknowledge anything significant in my life, I'm not going to criticise their method of doing it. My mother passed away last summer from a sudden illness, she was only 61 and my DB and I had to make the horrible decision to take her off life support. I got support and condolence messages all kinds of way - cards, texts, Facebook messages, e-mails, phone calls, and I was grateful for the outpouring of support we got. Same thing if that's how someone chooses to keep me in the loop. They thought of me enough to keep me in the loop. I was notified at 4am via text that my niece was born. I got immediate notification with a picture, and was just happy for my DB and SIL and excited to meet her.
It might be a generational thing, but it's the reality of the day and it might overlook someone's genuine concern and intentions to dismiss anything electronic.
