I am coward

Something bad happened this morning but luckily I had dealt with it. I don't get it why there is always people who like to take things for granted. They just pisses me off every time! Plus, I don't like people who borrowed my book and never return it to me until the last minute. During the morning study time, our form teacher told us that don't be a coward, just say it out what you feel. Just say it out? Is that so?? What if we expressed our true feelings? I can imagine that. *BOOM* Conflict appears! Anyway, whatever they are doing is none of my business because I am coward. :)
