Importance of the correct Email address

A man checked into a hotel.There was a computer in his room, So he decided to send an e-mail to his wife. However, he accidentally typed the wrong e-mail address, and without realizing his error, he sent the e-mail.
Meanwhile.....somewhere in Houston, a widow had just returned home from her husband's funeral. The widow decided to check her e-mail, expecting messages from relatives and friends.
After reading the first message, she fainted. The widow's son rushed into the room, found his mother on the floor, and saw the computer screen which read:

To : My Loving Wife
Subject : I've Reached
Date : 16 May
2004
I know you're surprised to hear from me. They have
computers here now, and you are allowed to send e-mails to your loved
ones. I've just reached and have been checked in. I see that
everything has been prepared for your arrival tomorrow. Looking
forward to seeing you then! Hope your journey is as uneventful as mine was.
P.s It is damn hot down here !!
