A man is in his front yard when his attractive neighbour comes out of her house and heads to her letterbox.

She opens it, looks inside, slams it shut and storms back inside. A little later, she come back out again, goes to the letterbox, opens it and again slams it shut.

Angrier back into the house she goes. A short time later she come out again.

She marches to the letterbox, opens it and then slams it closed again even harder then ever. Puzzled by her actions the man askes her

"Is there something wrong" she replies "There certainly is! My stupid computer keeps telling me that I've got mail."
