I was going through my old address book (yeah, the one with little pieces of paper sticking out, with phone numbers forgotten, and addresses that are no longer valid). I was looking at the names of friends and past acquaintances and realized something. Those I keep as friends run the gamut from red necks to nerds to millionaires. But they all have one thing in common. They are true to their word, hold up to a promise, and keep the vows and oaths they have taken.
