I avoid it. I've been on it a few more times this week, since I joined a group. And if I'm on, I will send birthday wishes and stuff. My DIL is on there, and she will tell me to go look at various photos and videos of the grandkids.
Plus my 15-yr-old granddaughter recently joined, so I send her subversive leftist political stuff! Like AOC's speech to Congress the other day. She likes it!
We had a conversation the other day - an actual conversation! - about politics and she's quite interested. I'm not an expert at all, but she wants me to send her stuff. She was supposed to give me her Instagram info, but she (conveniently?) forgot.
