Both play soccer with a passion. I could go on and on. But let's stop here. The differences seem to completely separate them. Joe is very religious, and goes to church every morning.
P is an atheist, who believes that religion hobbles free thought.
Joe is devoted to his family, and very attached to his friends. P is uncomfortable with the concept of devotion and claims to be, in the ultimate analysis, alone. Joe's father was the captain of a ship and has sailed the seven seas. Joe, however, has a very strong anchor at home in Madras, India. P's father is is Cambridge-educated academic who was always on a university campus.
