Remember the Prodigal Son?

Do you remember the parable of the Prodigal Son?

Long story, short.  There are two brothers.  The younger brother asks his Father for his portion of the inheritance and wastes his fortune on drugs, wine and women.  The older brother stays home and works the land for his Father.  The younger brother realizes his mistake and goes home and repents to his Father.  The Father is elated and throws a huge party for the younger brother.  The older brother is pissed off.

My question today is which brother am I?
