For example,

• When a carpenter wants to eat in a restaurant, a

chef prepares food for the carpenter. In this way,

a chef is helping a carpenter.

• When a chef needs or wants to repair a

furniture, she or he goes to the carpenter. And

here the carpenter helps the chef.

• A doctor treats a teacher and a teacher teaches

the doctor’s children.

• So, we can see both are helping each other or

we can say both are interdependent on each

other.
