Everybody makes mistakes, I bought sour milk once, it'll never happen again. Your mom fucked a deadbeat and was left with you. The milk, like you father, is gone, only thing is I can go buy a new jug and be happy with my milk, you, you're stuck not knowing your dad for life. And even if you do eventually meet him, you have to deal with the fact he never loved you enough to raise you. I win, you fail at life.
