They will be happy if they do not have to work for their every bite of rice. They will be happy if they do not have to go hungry to work becasue yesterday was rainy day and they could not earn money. They will be happy if they will be kids and have no responsibilities than study and play and little chores around the house. No one is happy but it is not fair that kinds in just a young age have to work for their food. Can't imagine how bad it is to be born very poor.
