Your post made me laugh. because I still struggle with these rules. And apparently I am of that generation.

My last BF texted quite often. Pretty much all day long until we spoke on the phone or saw eachother. He would literally leave my house and call me on the way home too. he is a millennial without kids, lol. I felt bad not being able to keep up and my work even suffered for it. And my girls weekend away was him texting me constantly. And with kids.... not easy. But he established a frequency of texting and when it deviated I had all those dumb questions run through my head.

I've been trying to figure this stuff out for years. And it is fascinating in a frustrating sense.
