Listen and chant.
I'm in a foreign city with busy streets.
There are lots of people and things to eat.
Wow! These things are all very new.
What do I say and what do I do?
Say, "Excuse me," and "Pardon," 

And "Nice to meet you."
Take messages, shake hands
And close your mouth when you chew.

And line up, too.
When you are polite to others,
They'll be polite to you, too.
