Advice concerning the suitability of a mate turned on its head

The grandmother speaks to her granddaughter: When I was a girl the best advice from a loving parent concerning, A suitable mate for their daughter, Was 'find someone your own age', Don't fall for someone twenty years your senior, Now, well, if he is in good health, young at heart with a good sense of humor, I say don't write him off, When there are so many young ones who will never reach fifty. And then there are the other ones who are just plain full of it, With their only interest in life being, themselves., And the attitude that the world owes them a living because they are entitled. If you love him bring him to your granny, I have plenty of wood that needs chopping, And fences to mend, There is a dance on Saturday too, And if he can make your Granny laugh, He just might be good enough for you.
