India: Hello sir, my name is XXX and I am calling from Microsoft because we are getting errors on our servers from your computers.
Me: You are from Microsoft?
India: yes sir, I am calling you about errors on your computer.
Me: But I don't have any errors on my computer.
India: Yes sir, but it is producing errors here. Do you have long start up times and other program shut downs or things that you cannot explain.
Me: No, my computer is behaving beautifully. No errors or anything like that.
India: OK sir but it is producing errors on our servers. There is something wrong with your Windows and we are checking through your license number and find that it is something wrong with your computer.
Me: Are you sure that it is my Windows computer that is causing all these problems,because I am not using Windows?
India: Yes sir, it is definitely your computer and it is having problems right now.
Me: Well I am actually using my computer right now and I am not having any problems with it at all.
India: Yes sir, we can see on our servers that your computer is giving us problems.
Me: Well I can't understand why my computer is even connected to your server.
India: yes sir, it is and it is giving us problems.
Me: I don't understand how my Linux based machine is giving Microsoft any problems.
India: Yes sir it .... pause .... penny drops ... beep beep beep. :)
