"A son is a son until he takes a wife but a daughter is a daughter for life."
- attributed to the Irish
From the father of three little girls, I can attest that there is something wonderful in the relationship between fathers and daughters. May you experience that in the fullest measure in the years to come.
And the one piece of advice about daughters that I will pass from a man far wiser than myself, if there is only one thing that you do for your little girl - don't let her marry a loser. Everything else is probably details.
