I never saw my dad cry. My son saw me cry. My dad never told me he loved me, and consequently I told Scott I loved him every other minute. The point is, I'll make less mistakes than my dad, my sons hopefully will make less mistakes than me, and their sons will make less mistakes than their dads.
The belief in some being who can be the judge of all human matters is a very comfortable one - all wrongs will be righted and all rights will be rewarded.
