Because the mother had nothing todo with her upbringing right?
You know - for a father, you have a lot to learn about kids.
There is only so much that nurture will do. You must have noticed your own child has developed a personality. Now, when you have a second child, you will find they have a totally different personality. So all that back-patting you are doing right now over your kids development - well, you can stop right now 'cause it ain't you at all.
Some people just grow up being cnuts and there is nothing you can do about it.
