Moral Story: Just do not conclude that you know everything

One truck driver was doing his usual load delivery at
a mental hospital, by parking his vehicle beside an
open drain.
He discovered a flat tyre when he was about to
return from the mental hospital. He jacked up the
truck and removed the flat tyre to fix the spare tyre.
When he was about to fix the spare tyre, he
accidentally dropped all the 4 bolts in the open
drain.
As he cannot fish out the bolts from the open drain,
he started to panic as to what should be done.
Just then, a patient happened to walk past him and
asked the driver as to why he was looking troubled.
The driver thought to himself, since there is nothing
much he can do or this mental joker can, just to
keep the bugging away, the truck driver informed
the whole episode to the mental patient and gave a
helpless look.
The patient just laughed at the truck driver and said
”You just cannot even fix such a simple problem. No
wonder you are destined to remain a truck driver
for life”.
The truck driver was astonished to hear such a
comment from a mental guy.
“Here is what you can do” said the mental guy…”
take one bolt from each of the remaining 3 tyres/
wheels and fix it on to this tyre. Then
drive down to the nearest workshop and replace
the missing ones. Isn’t it simple my friend?”.
The truck driver was so impressed with this quick fix
answer and asked the patient ”How come you are
so smart and intelligent and you are here at the
mental hospital?”
The patient replied ”My dear friend! I stay here
because I am crazy but not stupid”.
No wonder, there are some people, who behave
like the Truck Driver, thinking that others are just
stupid.
So, guys, though you all are learned and wise, but,
just watch out, there could be some CRAZY guys in
our professional /personal lives, who could give us
lot of quick fixes and brush our wisdom.

Moral of the story:
Just do not conclude that you know everything
and do not judge people by mere looks/attire/stature or academic background.
