F-factor
The F-factor is the rating you get based on how much of your life you're willing to waste on a friend.
I gave my friend a 1 because he still thinks we're close after I blocked him.
My F-factor is 10 because I would die for my bestie, even if he stole my lunch money.
My cousin got a 2 because he only texts me when he needs a ride to the mall.
