I was walking the passageway connecting red line and blue line this evening.
Then this person intentionally tried to trip me from behind, I did not fall but as I looked back, he and 2 other men were laughing at me.
For a second, I was really angry — I wanted to yell at him and punch him. But instead, I decided not to do anything. It is not worth causing a trouble, I have a lots of things that are too important.
