This reminds me of a bit of my family. I was probably in one of the earliest college cohorts that got email addresses, and so my mother and I would send multiple emails throughout the day M-F (usually around breakfast, lunch, and before dinner, as my mom didn’t have a home email address). These generally weren’t long messages, but messages nonetheless. (And they were free! Unlike long distance calls, which we only did weekly.)
My uncle, who had 3 sons, the youngest of which was a year older than me was amazed. He was like, “What do y’all have to talk about that often?” 
I guess we were one of the examples that uphold the stereotype.
