Ok i will put my own answer here!
Injustice makes me cry the most, either done to me or to others. Death of someone I love or something really bad happening to them. If my mother or father cries, I can't help but cry with them. Lastly, parting from someone I love after spending so much time together!
I rarely cry, maybe once or twice a year.
I never want to cry or even have tears in my eyes in front of someone I work with.
