In the big city of New York, Romance and Adventureare always waiting.
As we walk along the street, they are watching us.We look up suddenly and see a face in a window. The face seems to interest usstrangely. Or in a quiet street, we hear a cry of fear and pain coming from ahouse where no one lives. A car takes us to a strange door, instead of to ourown. The door opens and we are asked to enter. At every corner, eyes looktoward us, or hands are raised, or fingers point. Adventure is offered.
But fewof us are ready to accept. We are ready to do only the things we do every day.We wish to do on-ly the things that everyone else does. We move on ；and some day we come to the end of a long quiet life. Then we beginto think. Then, when it is too late, we are sorry that we have never known trueRomance and Adven-ture.
