4 years old:  My daddy can do anything.
 5 years old:  My daddy knows a whole lot.
 6 years old:  My dad is smarter than your dad.
 8 years old:  My dad doesn't know exactly everything.
10 years old: In the olden days when my dad grew up,
                     things were sure different.
12 years old:  Oh, well, naturally Father doesn't know anything about that. 
                      He is too old to remember his childhood.
14 years old:  Don't pay any attention to my father.  He is too old-fashioned!
21 years old:  Him?  My Lord, he's hopelessly out-of-date.
25 years old:  Dad knows a little bit about it, but then he should because
                     he has been around so long.
30 years old:  Maybe we should ask Dad what he thinks.  After all, he's had
                     a lot of experience.
35 years old:  I'm not doing a single thing until I talk to Dad.
40 years old:  I wonder how Dad would have handled it.  He was so wise
                     and had a world of experience.
50 years old:  I'd give anything if Dad were here now so I could talk this
                     over with him. Too bad I didn't appreciate how smart he was. 
                      I could have learned a a lot from him.
