A: May I ask what street we are on?
B: You are in the middle of 5th Avenue.
Which way are you going?
A: I wish to go to the Public Theater.
B: Keep straight on, and turn right at the third corner.
Go two blocks and you come up to a bridge.
Cross the bridge and make a left turn...
A: I'm sorry. I'm confused. Would you draw a map
for me?
