Imagine standing on top of the Empire State Building in New York city. You and your friend are both looking down at the city through the big binoculars (never mind in reality if they have these up there, my visit was long ago). You are standing next to each other, both pointing your looking devices towards different directions.
“Wow, there is so much green and forest in New York City!” says your friend, who is looking towards the Central Park.
“No there isn’t, there’s only dusty streets and no trees at all!” you answer, pointing your binoculars elsewhere.
