     We tried so hard to make things better for our kids that we made them worse. For my grandchildren, I'd know better. I'd really like for them to know about hand-me-down clothes and home-made ice cream and leftover meatloaf. I really would.

     My cherished boys, I hope you learn humility by surviving failure and that you learn to be honest even

when no one is looking. I hope you get a black eye fighting for something you believe in. I hope you have

to share a bedroom with your younger brother. And it is all right to draw a line down the middle of the

room, but when he wants to crawl under the covers with you because he's scared, I hope you'll let him.

And when you want to see a Disney movie and your kid brother wants to tag along, I hope you take him.

     I hope you have to walk uphill with your friends and that you live in a town where you can do it safely.

I hope you learn to dig in the dirt and read books, and when you learn to use computers, you also learn

how to add and subtract in your head.

     May you skin your knee climbing a mountain, burn your hand on the stove and stick your tongue on a

frozen flagpole (旗杆). I hope you get sick when someone blows smoke in your face. I don't care if you

try beer once, but I hope you won't like it.

     I sure hope you make time to sit on a porch with your grandpa or go fishing with your uncle.

     I hope your mother punishes you when you throw a baseball through a neighbor's window, and that

she hugs you and kisses you when you give her a plaster of pared mold of your hand.

     These things I wish for you-tough times and disappointment, hard work and happiness.
