Homework for 13th class

i don't think there's any examples near me, but i know many government officials are greedy ,they earned many money and those money doesn't belong to them. many of them are arrested, but others are still in the government or company. 

I become greedy in front of lots of food, that's why I get so heavy now.Once I had afternoon tea with my friends, they did the talking and laughing but hardly ate some food such as pizza or cream soup. Unlike them, I grabbed a handful, and ate almost half of their food.(Everyone ordered their own food, but they agreed me to have their food because I looked so hungry.) After having the food, I went home and found my belly aching. I have to eat some pills which were so bitter and acid so that the food could be digested.

Although my greed of food caused a small or harmless result, I learnt to be reserved since then.
