How many chances do you give a person until you give up on them?

I never give up on anyone. I know what it's like when someone gives up on you, and all it does is make you worse. When you're in a terrible place, people's belief in you may not help much, but when you lose it, it fucks you up.

as many as I want to give them.. zero to several hundred :)

It depends if they are good at pissing me off then even one will do

My boss would say Zero, because after working for him for almost 3 years and never missing a day, or ever being late, the 1st time I legit got sick and told him how sick I was a day and a half a head of time, he said "either you show up or you're fired."

too many, so it seems

If it's family i would not give up others till they really piss me off so bad

Good question. My biggest flaw seems to be giving unlimited chances.

Depends on who it is and what they did.

Too many
