Excellent story of Moral ethics

John worked at a cold storage. One day, when he finished with his work
schedule, he went into the cold room (Freezer) to inspect something but in
a moment of bad luck, the door closed and he was locked inside with no help
in sight.

Although he screamed and knocked with all his might, his cries went unheard 

as no one could hear him. Most of the workers had already gone and outside 

the cold room (freezer), it's impossible to hear what was going on inside.

Five hours later, whilst John was on the verge of death, the security guard
of the factory eventually opened the door and saved him. John then asked
the security guard what he came to do there as it wasn't part of his work

He replies: "I've been working in this factory for 35 years. Hundreds of
workers come in and out every day but you're one of the few who greets me in the morning and says goodbye to me every night when leaving after
working hours. Many treat me as if I am invisible. So today like every
other day, you greeted me in your simple manner "Hello" at the entrance
when resuming for work. But curiously after working hours today, I observed
I've not heard your "Good bye see you tomorrow". Hence I decided to check
around the factory.

I look forward to your greetings every day because to you, I am someone. By
not hearing your farewell, I knew something had happened. Then I sought and
found you!

Moral Lesson:
Be humble, love and respect those around you because life is too short. 

Try to have an impact on people in ways we can't even imagine especially

the people that cross our path daily.
