Do y’all have conversations in your heads, cause I do!

I always have conversations in my head and they feel very real. I’m going to tell you just how real.

Today, I was angry with my brother so I started formulating a response so I would be ready if he decided to continue the argument. He never did, but that didn’t matter because I was arguing with him in my head. I was so caught up in the “argument“ that I almost responded to my actual brother instead of the one in my head. Does this happen to anyone else?
