My plan was to build a garden walkway made up of wooden squares. I decided I'd slice railroad ties into two-inch-thick pieces. That's what I told the clerk at the lumberyard. “You got a power saw?” he asked. “No,” I said. “Can't I just use my hand saw?” He nodded slowly. “You could. But I just have one question. How old do you want to be when you finish?”
我的計劃是用木頭方塊鋪一條花園走道。我決定要把鐵路枕木鋸成兩寸厚的木塊。我就是這樣告訴木材場的職工的。他問：“你有電動鋸嗎？”我說：“沒有。我不能用手工鋸嗎？”他慢慢地點頭說：“你能用。不過我有一個問題：你準備多大年紀的時候完工？”
