Even though I just had lunch not long ago，I was felling hungry again．I went for something to eat．That was when I discovered the pudding in the fridge．It was made from milk，sugar，eggs and fruits，and it looked so yummy．I noticed that there was only one left．

I was putting the pudding on a plate when my brother came into the kitchen．He found the pudding and asked for it．"It's mine!I was the only one who found it!"I shouted．"You are my elder brother，You should give it to me!"said he．Then he started pulling the plate towards himself and I did the same．

Suddenly，the plate moved to one side and the pudding slipped （滑动） out of the plate．It landed on the floor and turned into a yellow mess．My brother and I both looked at each other，feeling amazed and disappointed at the same time．It was such a waste!

To my surprise，Ollie，our pet dog，walked over to the mess on the floor．It began to lap up the pudding happily，Within minutes，the mess on the floor was gone．Ollie licked （舔） its lips when it was done．

After watching Ollie finishing the whole pudding by itself，we realized     ．If both of us had shared the pudding，we would both have got to eat half of it．It was because of our greed （贪婪） that we ended up with nothing．That day，my brother and I learnt a good lesson．
