Just FYI, Not everyone feels jealousy like you're suggesting here.

I know I never have. I never understood why people get so worked up about that sort of thing honestly. It never bothered me if someone wanted to date my ex, or if they had some sudden windfall, or are doing well.

But I see some people feel this intensely! I'm sympathetic, IMO, they don't choose to feel that way. But it's funny to me, if I were to walk down the street and see two people, and give each of them $5, it would be all smiles. But for a certain percentage of people, if I gave the person on the left $5 and the person on the right $100, they'd feel worse than when they had no money!
