since when i started to become---残忍?

Since when i started to become, so mean?so cruel?so cold-hearted?
I don't like to be like that.
Yes, i am cruel when something disgust me.
Yes, i am cruel when i feel being manipulated.
讨厌人家利用我.
讨厌自由被剥夺.
想用眼泪博取我的同情心?
真的很不爽! 这样只会加强我的保护层.
There is still a border, which we are prohibited to cross.
I will nurture a strong heart. To say NO.
