Some people in this world are kind,helpful,caring...But don't be deceive by their looks.On the outside,they look caring,but in the inside,they have a rotten heart.An example is when an old man boards the MRT.Some kind-hearted people are willing to offer their seat whereas some people would pretend not to see the old man and continue staring into space.This is what most teenagers would do.~pretend as if nothing happens~
