I am Alice. My sister and I spent our last weekend with our uncle.
Our uncle bought us two bags and asked us to go to the mountain with him. When we walked, he put stones (石头) in our bags. To our surprise, he also took some stones out from our bags.
When we went home, we were very tired. Our bags were full. But our uncle's bag was half full.
“Why did you give us so many stones?” we asked.
“You didn't know it, but I gave you a test today. Whenever you complained (抱怨), I put a stone in your bags. Whenever you were positive, I took out a stone. And now look at your bags.”
Our bags were full of stones.
“Your negative (消极的) thoughts are just like stones. The more negative thoughts you have, the heavier your mind will be,” said our uncle.
Our uncle taught us one of the most important lessons in life.
