The toppings you may chose for that TV dinner pizza slice when you forgot to shop for foods, the paint you may slap on your face to impress the new boss is your business.

To short sentences, to many headings, images too large for the proposed design, or too small, or they fit in but it looks iffy for reasons the folks in the meeting can't quite tell right now, but they're unhappy, somehow. A client that's unhappy for a reason is a problem, a client that's unhappy though he or her.
