Why do people write? Why do you write?

I feel more free when I write than I do just speaking. It’s hard to explain, but sometimes I almost feel like I can’t be myself when I open my mouth, but who I really am comes out when I’m writing. Sometimes I write to entertain others, or sometimes I write things that probably wouldn’t make much sense or be interesting to most people outside of my own head, but either way, I feel like I just need to do it sometimes.
