The word "DADDY" is not defined by weather or not a man has a biological child. You can never produce a child and be a "DADDY", like wise you can have 20 kids and never be a "DADDY"..
A "DADDY" is a man who cares for a childs both physical and emotionals needs. He uts the childs wants and needs ahead of his own.
A "TRUE DADDY" IS HARD TO COME BY, BUT A TRULY SPECIAL THING.
HAPPY FATHERS DAY TO ALL TRUE DADDYS.
