Can I be jealous of a guy known as 'Pokie' right now?
Maybe. Why are you jealous of him?
I think he is very pretty and all the people just adore him to death.
Attractive people can make anyone jealous, you are no exception. Jealousy is a terrible trait, it eats you alive if not taken care of. Be yourself and let others have their fame and fortune, it won't last forever.
You are right. I would enjoy seeing his downfall.
Well it is not good to want to see his downfall, it does not look good for you. And being jealous is such a negative emotion that you might want to avoid showing.
