Danna, thank you for reading and commenting. Everyone ages differently. It is, of course, the experiences you have during those fateful 20 years that make a difference. I mentioned music and online competitive gaming, as some examples, but there are many many more. If my friends were into similar things no matter their age, I assume I would not find age makes much of a difference. I don’t follow popular culture at all, don’t watch TV, so I am lost when those things are discussed. If your point is that if you keep up with current popular culture — or things in general — you would not have fewer things in common. Good point.
