Hello and welcome to RPG! Haha, I love your introduction! If you're wanting to write a paragraph or two and are writing at the level you've just shown, I believe that Casual will be much more of a fit for you but by all means feel free to test out the waters of Free (as well as the other sections if you are daring). I hope you enjoy your stay here and will find a few roleplays to quench your thirst for writing. If you have any questions at all, feel free to ask and I'll be more than willing to help out.
