 Microsoft? Is that a city in Pakistan? No, ma'am. Microsoft, the computer company. I'm calling to tell you we have found a problem with your computer. Really? That's quite concerning. Yes, madam. It can become very serious indeed, but thankfully I will be able to fix it for you. No, I meant it's very concerning because I don't have a computer. You don't? No. Oh, must be a problem on your laptop, madam. I don't have one.
