Yeah. Make sure you've got it recorded somewhere. Dad died 20 years ago when I was a kid, and I have to approximate what he sounded like in my head. It sucks.
A typical conversation with my mom starts with:
Answerer: hey what's up
Caller: not much, do you want to chat?
Then we chat for 10-40mins about whatever, then say bye. It's nice to feel connected to people in your life.
If either doesn't want to talk we just say, not a great time. Reply is always no worries, chat another time, bye.
