'Yes Dear'

I provide technical support for the computer software published by my company. One day, over the phone, I was helping a customer install a product on a Macintosh. The procedure required him to delete an old file. On the Mac there is an icon of a trash can that is used to collect items to be permanently deleted. 

I told the customer to click on the old file and drag it to the trash. Then I had him perform a few other steps. As a reminder, I said. 'Don't forget to empty the trash.'

Obediently he replied, 'Yes, dear.'
