As Computer Tech I sometimes help clients over the phone. Here is a recent phone dialogue I had with one of my customers.

Tech: Workshops can I help.
Customer: My dog is not barking, how can I make it bark.
Tech: I am sorry mam but this is not SPCA
Customer: I know that but how can I make the dog on my computer bark.
Tech: Do you mean a dog in a computer game or something?
Customer: I mean a small dog that comes on when I type in Microsoft Word.
Tech: Are your speakers on?
Customer: No
Tech: Turn on your speakers and you will hear your dog barking when it barks
Customer: Ooooh why didn’t I figure that, thanks so much
