Bim, PM if you wish! Introverts can still talk on the phone.
I had a long conversation with an old pal the other night. He called me up because he's on furlough from his job, lonely, needing friends. It was good to hear his voice. We do text every so often. He's one of us. Not sober at the moment, though. I'm hoping to get him back to wanting to be sober - he's not sure he wants to right now. There are no F2F meetings where he is right now and he doesn't really want to do remote meetings. I think he will get back to it eventually. I hope.
