Yeah, I like some alone-time smoking, too. Plus I can talk to myself out loud and no one will be all "That's not very healthy. You should get help."
My bf and I have different hours. He likes to get up really early and go to bed really early. I usually go to bed between 3 and 4am when I force myself to do the things I need to do to make my body sleep. Then I sleep til around 10 am. So I do smoke by myself a lot in the evenings. We will smoke together in the afternoon.
I wish I had people to smoke with, but that's never really been part of the deal for me. I live in a small town and have to drive everywhere, so it's a lot easier just to wind my days down by myself.
