Incorrect. Try Again!

C, is the correct answer. Ignoring what was said. Every response but ignoring acknowledges the existence of the other person. Ignoring says, "you're so unimportant, you don't exist"; the absolute worst message you can send someone. It doesn't matter why you ignore, it "ticks people off." Try it...you'll see ;-) On the other hand, the very best thing you can do each day is to be the first one to say "hi!" to everyone you meet.
