Melih,
Sorry, but you are wrong.
When the children leave home, you suddenly have more disposable income. You can buy a new van (I did

) , you can buy new sails (I did

) and you can buy new boards (I did

)
You will also find that your wife is not interested in windsurfing, so she can stay at home whilst you ogle the Pretty Young Things at the beach (I did and I do

).
When will all this happen, I hear you ask? Well, the last girl of mine left home when she was about 25, so Spunik, put up with the inconvenience and know there is light at the end of a l-o-n-g tunnel.
