I honestly couldn't imagine being a happy, or happy enough, person if I didn't have a good sense of humor, or if I didn't surround myself with others who could share in and likewise appreciate that. I guess if I wasn't saying this about myself, I'd be a different sort of person anyhow and perhaps this wouldn't apply. I'm not the most optimistic person. I've spent so many hours, since I was really young too, worrying about all sorts of big, unanswerable things (like mortality, our existence, for an obvious one), and I sure worry a lot about the current state of things for the planet, humanity, US and other politics, etc.. If I couldn't laugh about those things too, if I couldn't look at the sad but clear humor in any of this--well, humor is something that keeps me going, for sure.
In general, I'm not always the best at making jokes with others besides family or closer friends because I calculate my actions much more. And also, jokes are only good and only happen for me if they just flow naturally. I'm always ok with, and enjoy, being kindly teased or joked with, and would expect to be able to do the same. I love being made to laugh, laughing at myself, making others laugh.
