<human>: For context, I'm 22 and male, in the USA. Growing up, i was very socially...uninvolved. I cared more about reading. Then in high school, I got into social crowds by being a 'class clown'. I never stopped though. I realize that I say things that are hurtful, and I would have trouble forgiving them if they were said to me, but in the moment, I think they're funny, and they just come out of my mouth. I feel like I'm still a teenager. I attribute much of this to being very isolated most of my life, surrounded by people of a religion I no longer follow. But that's not an excuse, and I want to change. I just need help figuring out how to approach it.

Give me the gist of the text in a nutshell
<bot>: I never quit being a class clown, and now that I'm 22, it makes me an asshole. How do I change?
