Wait what just happened?

Ok so at dinner, my 55year old mother gets a phone call from her 70 year old mother, in-which  my Nana (in my mom's words) made her (mom) feel guilty about not replying to a text message she had recently sent to my mom! The phone call lasted all of 10 seconds, mom said she was sorry and said she was busy and the phone call ended.

I was sitting there taking it all in, wondering why the two did not just have a real life phone conversation about the topic of the text message. Instead mom replied to the text message and then Nana texted back merely saying "call me." So mom called her back and they talked.....oh technology and irony.
