A father and his son were leaving the market, their bags were full of groceries, "daddy, I want to use the restroom! " said the son.

The father who was eager to get home hesitated. He then said" Alright son, lets find a toilet quickly." He placed their bags carefully on a nearby bench.

They returned a few minutes later to find the bench empty. Someone had taken their groceries. The father stood for a while without moving. His legs became too heavy to move as if he was stuck to the ground.

The father opened his mouth to talk, instead of shouting, he bent down, wrapped his hand around his son trying not to show his frustration and anger. He said, "don't worry son, I will get you new groceries and new set of school kits".

The boy went back to school at the beginning of the term with his new set of school kits

At school, he made new friend's and took his studies seriously. He wanted to be a scientist and make his father proud.

Two years after he entered the university, his father who was his hero died after a prolonged illness. He promised that he will invent a vaccine that will cure the disease that killed his father so that he can save other people from dying.

Years later, he started working as a scientist. He did several experiments in the laboratory and later, he came up with the vaccine. He was glad the vaccine saved the lives of many people.
