An oak tree and a rosebush ...

An oak tree and a rosebush grew, Young and green together, Talking the talk of growing things- Wind and water and weather. And while the rosebush sweetly bloomed The oak tree grew so high That now it spoke of newer things- Eagles, mountain peaks and sky. "I guess you think you're pretty great," The rose was heard to cry, Screaming as loud as it possibly could To the treetop in the sky. "And now you have no time for flower talk, Now that you've grown so tall." "It's not so much that I've grown," said the tree, "It's just that you've stayed so small.

How many slams in an old screen door? Depends how loud you shut it. How many slices in a bread? Depends how thin you cut it. How much good inside a day? Depends how good you live 'em. How much love inside a friend? Depends how much you give 'em.

I believe that if you don't want to do anything, then sit there and don't do it, but don't expect people to hand you a corn beef sandwich and wash your socks for you and unzip your fly for you.
