Preparing to be Embarrassed

Okay. So Libby takes her out in public and she yells, "Is that woman black? I can see her boobs!"

Does that bus say, "Only white people can ride it?"

"Yoo hoo! Waiter! I need some more coffee!"

"Libby, the razor works really well on your armpits!"

I'm basically a very shy person. Can I do this?
