Here's a dilemma: If someone comes up to you and starts talking to you SO LOUDLY that you get embarrassed, what should you do?

A. Act like they're talking in a normal manner, because they probably just talk that way.
B. Grimace and take a few obvious steps backwards.
C. Shout back at them when you respond.
D. Say something witty, like, "I'm not deaf, ma'am." or "You got a volume knob on ya?"
E. Run away.

Personally, I like choice C.
