We bought a second-hand house, and that afternoon I was in the workshop of the gqrage,I noticed a part of a carpet sticking out of the ceiling of an attic(阁楼)that was strange, I found a ladder and headed up.

I climbed into the attic, As my eyes adjusted to the dark , I saw a metal container, I opened the lid and was shocked by  what I saw: several rolls of money tied up in orange string , I’ve found , like $800, Awesome!

But there was more than one box of money , I found another seven boxes full to the top, plus two big black bags full of cash, I won’t lie , My first thought was that this was a bleesing from God –the means to fix up this old house; or just to uxe to make life easier for our rwo young sons , who sere seven and four ,But I knew that the right thing was to return the money to the previous owners . So I called them and asked them to come.

They were shocked, of course, not only about the money but that I was returning it , They had recently got the house from their dad and said it must have been their dad who, had hidden the money, What made him do it? I thought about the hundreds of times he had bone to his shop, cut off a length of orange string ,and bound up a roll of money , I like to think he did it for his chileren .

There were balls of that ouange stuing still hanging on the wall of the workshop when we moved in ,I used them to tie up Christmas presents last year, for my kids , I hope it reminded them of the gift greater than money that my wife and I gave them by returning the money ,We did the right thing ,and our children will never forget that.
