Three friends lived in the same flat on the 110th foor
One day the lift wasn't good so they have to climb the stairs
To pass their boring time and make use of time into a interesting moment
they decided to tell story
So the first person should tell a war story
and the second a funny story
the third a sad story.
So the first person tells a story and they climd to 50th floor
The Second person tells his funny story and they reached the 109th floor
Now the 3rd has to say a very sad story
You know what was happeng?
..He says..
"I've kept the door Key in the car"... LOL
