Envy not necessary!
I hate envying things I don't need. *cough cough* Couples! Relationships! *cough cough* But then I probably know that when the moment I get asked, I'd probably reject it? Anyway, I know getting hooked up isn't the way of falling in love or like with that person, you've got to find it in them before. But, I guess you just feel the need to have fun with the opposite sex and not having anyone by your side can get pretty solitary.
