Nice meme!
Yep I know how to pray the rosary; I've been Catholic my whole life. I really need to start praying it every day though. I'm going to try and start that now that it's the month of the Rosary.
As for a favorite mystery....hmm...I don't think I could pick just one. They're all important in different ways. I really like the luminous mysteries though.
Also, when I don't have time to pray a whole Rosary, I love praying the Chaplet of Divine Mercy
