Envy: the only one of the 7 deadly sins where you don't get to have any fun.
There's always a little jealously of those who live a nicer lifestyle, isn't there? Heck, I'd love to have a nicer house (aka one with a bigger garage

), live in a prettier neighborhood, have the ability to go on exotic trips, have a vacation house, etc. But not enough that I lose any sleep over it or wish others ill-will.
