　　On the third Sunday in June, Americans take time to recognize and thank a special person in the family — fathers! Father’s Day celebrates the importance of fathers, young and old, and the men thought of as father figures.

　　＂Like father, like son＂ is probably the most common father expression. It means a boy is very much like his father, and sons often do what their fathers did before them. This can be a good thing or a bad thing.
