Oh yeah thats a good way to practice your communication skills. It'll also help you to learn how to master the art of the conversation and help you think clearly, I do it all the time. Totally normal!
Haha I do that. I used to do it more often because I got into a shitty relationship that lasted 4 years too long. Must mean you're optimistic. Er... maybe neurotic. Either way I think it's normal.
