I get jealous occasionally. But not to the point where I let it control my mind. Sometimes I would joke around with it, but whenever I do people get a bit uncomfortable with the joke. I know Envy is a sin one should never have due to the punishment of being eternally damned, but there are some people out there who never realized that they are doing a deadly sin. Like for example, I never knew I was being a gluttony until later in life when I was 12. So i'm not sure if people would know any better about the sins they have. If you ask me, I say the deadly sins are inside all of us, just waiting to be released or to be purified by god himself.
(Sorry, I'm a Christian...sometimes I get carried away with my religious talk XD)
