F.I.W.D.
A friend that you would totally do, but you’re too busy being friends to actually do it.
You’re at the restaurant and think, 'If I didn’t have a date, I’d be with them.'
You see them and think, 'They’re cute, but I’m already friends with them.'
You text them, 'You ever think about doing me?' and they reply, 'You ever think about being the best friend?'
