How dare you did this to me ???

I still wonder if everyone can speak good words, which do not hurt someone's heart everyday, every minute. It's such a good thing if everyone can do it. The whole world will not be so cold blooded. I have a friend (girl). Her mouth is very .... . I also don't know how to desribe it as well. What I know is that every word that come out from her mouth is so hurting. Today, she write something on a paper and give to someone . Luckily, the person who read don't understood. If not, I 'll be such embarrasing. Why don't she just think before act ? I'm now really angry with she but i have to be generous too. Takling just like no buying insurance, that can hurt someone so deep . I have to be strong whatever they did to me ... GAMBATTE !!!
