Is having a daughter different for a father than having a son?

Though they love both equally, fathers share a different rapport with their sons and daughters. Sons are treated more like "men" by the fathers. They talk to them, play with them, treat them more like their pals and once they start growing up they treat them as their friends. Fathers have a very soft corner for their daughters and treat them delicately, though I won't generalize. They are very protective, can't say no to them, and yes can be their friends too but the equation is a tad different than what it is with the sons.
