There is an old tree on a dry land. The tree has so many branches. It brings shadow (树荫) to hundreds of travelers.
One day, two travelers got to the tree. They walked for a long time in the hot sun. They were too hot and tried to find a place to rest. Luckily, they found the big tree.
They made a decision to take a rest under the tree. They slept there for a while. When they woke up, they felt hungry and one traveler climbed up the tree. But he was sad to see nothing.
He started to say bad words to the tree. "Oh, this is just a useless tree without any fruit on it!" The other traveler said nothing about the tree but asked his friend to be quiet. However, the traveler in the tree still shouted at the tree.
The tree couldn't stand the traveler at last.Hesaid in a sad yet strong voice," You can't be so ungrateful(忘恩负义的) to me, Just look back to the moment when you got here in the hot sun! I gave you a cool and comfortable place to rest. You would die now without me!"
Many people do much for us, but we sometimes forget to give thanks but only complain! Make sure not to say any bad words to the one who has helped you.
