Most people are not that--green with envy---bit, on occasion you do find some. Take this story:
You are a dancer, and you have a friend who is also a dancer. You get into a company and get your friend in as well. You say, "it doesn't matter we can get out of it because they are lots of opp's in this city." You and your friend get in and out within a month.She follows to another company, and another company, and to your own company. Everything is going well.......boom! She drops out of your company, gets engaged, becomes pregnant, gets married, and has a baby. Now, she is known as "ex-room mate". Why because she messed up your plans to conquer the "boss". You talk crap about her. Truth of the matter is you're sore because you could not deliver the goods.
A word to the wise: Be careful of what crap you talk about others--especially if people are always leaving.
And that is Green with Envy!
