A friend of my father called my phone:
She - I bought 3 desktops, a router and a internet service. 2 desktops doesn't connect to the internet!
Me - did you plug the router in the power-line?
She -Yes.
Me - And the cable from the internet company?
She - In my computer, of course!
Me - Plug this cable in the router.
She - No way! I paid for it!
I asked her to call the internet company... That's not my problem ,obviously!
