You've got mail

A man was in his front yard mowing grass when his pretty blonde neighbor came out of the house and went straight to the mailbox. She opened it then slammed it shut and stormed back into the house.
..

A little later she came out of her house again, went to the mailbox, again opened it, and again slammed it shut. Angrily, back into the house she went. 
...

As the man was getting ready to edge the lawn, here she came out again, marched to the mail box, opened it and then slammed it shut harder than ever.

Puzzled by her actions the man asked her, “Is something wrong?” To which she replied, “There certainly is! My stupid computer keeps saying, ‘YOU’VE GOT MAIL’.”
