Working in field

This is my field. These days this field is full of greenness. These are maize plants which are growing up now. These plants have planted one month fifteen days ago. There are three months are left to harvest.
My father is a farmer. He likes to farm more and more. Every morning he goes to field to observe what is the situation of crops. It is in good condition or not.
One day I want to go to field with my father so he took me with him and began to walk. He and me continuesly walk towards the field, we are about to reach the field I began to feel pain. But my father didn't feel any kind of pain . That time I felt that working in field is very difficult job.
