My dad was complaining how the younger generation doesn't answer their phone anymore and I had to explain it's all scam calls now and it's his generation that keeps the scammers in business
I'm likely your dad's age. Strange that he wouldn't get this concept. Even if you're in my contacts, I'll text before I call to ask if it's ok. Even with my own spawn, I don't just up and directly call her.
That's always seemed odd to me. I'm personally not a fan of texting, I always just call people. They answer or they don't, and they'll either call back when they're free or text and we go from there.
For friends my own age, we're all working sixty plus hours a week because hurray America and we live in different time zones. It's a mutual courtesy to set a time to talk.
