“I have lost and loved and won and cried myself to the person I am today.”
It isn’t fair!”
“No, it isn’t, baby. Not by a mile. The world’s only as fair as you can make it. Takes a lot of fight. A lot of fight. But if you stay in here, in your own little cave, that’s one less fighter on the side of fair.”

This is the kind of thing you say to a child who is suffering and complains that something’s not fair. You don’t tell that child some asinine remark like “Well life isn’t fair.” You help them through it and validate their feelings.
