A father and son relationship is completely different than a father daughters. The son is the one that typically carries on the family name. It is the responsibility of a father to turn the son into a man.
Dads want to pass on their knowledge to their sons if they have one. It is not that we do not want to pass this information onto our daughters its that we are not sure how too. Woman have a completely different set of emotions (not really, but it just feels that way at times), they are more sensitive at times, they have a different way of communicating, a different way of understanding, and sometimes dads are just at a loss.
Men are typically more aggressive than woman. I say typically, because there are situations were females are more aggressive than males. Men are typically more harsh/blunt, they typically communicate with few words, they do not express themselves well, there first instinct is destroy that which is hurting someone in the family versus being more nurturing and caring. This is what we pass on to our sons and potentially our daughters.
A father son relationship like a father daughter relationship is a special one, but a father and son will typically clash for a season or two, but will work it out so there is a mutual understanding which can lead to a strong relationship. However, it is possible that this clash could cause a fracture, so just be careful.
Sons are always seeking approval from their dads. Sons are always trying to emulate their dads. Sons will seek wisdom/understanding from their dads. Sons will discuss things with their fathers that they are embarrassed to discuss with their moms. Are you, the father, willing to be there for your son.
Are you having a problem with your son? Is it hard to communicate with him? If the answer is yes, that is ok, but just ask yourself why? Do not jump to the conclusion that it is your sons fault. Try to remember what you were like at his age. I realize this will cause you to dig deep into your memories, but it will help you to understand him. Also, remember that he is probably acting just like you, so take a step back and take a hard look at yourself.
