The Airport

This, from the internet:

A young lady was waiting for her flight in the boarding room of a big airport. As she would need to wait many hours, she decided to buy a book to spend her time. She also bought a packet of cookies.

She sat down in the armchair of the VIP lounge at the airport, to rest and read in peace. Beside the armchair where the packet of cookies lay, a man sat down in the next seat and opened and magazine and began to read.

When she took out the first cookie, the man took out one also. She was irritated but said nothing. But she thought: what nerve!

For each cookie she took, the man took one, too. This was infuriating her but she didn't want to cause a scene. When only one cookie remained, she thought to herself: Ah! What will this man do now?

Then, the man, taking the last cookie, divided it in half and gave her one half. That was too much! She was angry now. In a huff she took her book, her things and stormed off to the boarding place.

When she sat down in the plane and looked in her purse for her eyeglasses, to her surprise her packet of cookies was there, untouched and unopened. She realized that she had forgotten her cookies were put in her purse.

She felt so ashamed. The man had shared his cookies with her, without bitterness or complaint. And now there was no way to explain herself or apologize.

There are 4 things that you cannot recover: 

The stone after it's thrown;
          The word after it's said;
                    The occasion after the loss; and
                              The time after it's gone.
