"Can you make me an eye doctor appointment?"

I know, I know...This is not an odd request to make to one's personal assistant. However, it is a little odd to call your assistant and leave her a five minute message about which office to call, that you know your regular optometrist's office is closed, and a description of the reason you need an appointment in the next two hours, all when you know she is driving to Boston to deliver a table to an antique store for you while you sit in your office with full internet and phone access. Wouldn't it be a little easier to just make the call yourself?
