You are learning asking directions: you will read the scene it happens in, take apart the pattern behind them (directions), hear them in a conversation, rehearse them, and finish by saying one thing out loud to be graded.
New York City is a grid. Avenues run north-south; streets run east-west. "Go uptown" means go north; "downtown" means south; "crosstown" means east or west. Three phrases navigate the entire city.
Manhattan below 14th Street doesn't follow the grid — the streets of the Financial District and Greenwich Village are old colonial paths that predate the 1811 grid plan. Above 14th Street, the city locks into perfect perpendicular logic.
The stranger is somewhere below 14th, looking for the High Line. He stops a woman walking a very small dog. "Excuse me — where is the High Line?"
"The High Line? Go up this street — that's north — about five blocks, then turn left on 14th. You'll see signs."
"Five blocks north, then left on 14th. Is it far?"
"Maybe ten minutes walking. It's not far."
"Thank you so much!" The dog looks up at him. The woman smiles. "Enjoy the city!"
