I kinda remember back the moment me and my girlfriend went out for a date with her friends. Lots of fun we had and lots of nice memory we had back then, but still her face seems like missing something. Smilling but seems like smilling with no energy. Everytime when i sent her back, just before i leave, she always said: " William, you are a good guy." I though she was praising me, so i return her with a smile and she does it back, but in down expression. I still can't get what she mean back then, so with the following years. Even when we broke up, when i stop by at her house, she still saying the same thing. Last night, when a friend back at UNIMAS asked me for some help, and i do her a flavor. She said the same thing, "William, you are a good guy." After i notice what she said, i kinda remind what my ex gf said. Then i asked her back, " Why on earth i don't have a gf if i realy are the good guy you think?" She explain that i treat all people in a equal good, no matter who they are, girls wouldn't want it that way. Feel likes my good is belong to everyone, not she alone. Back then, i realise what my ex gf want to said. I really felt sorry for her. I don't know that being a good guy can hurt someone we love. This is a lesson we can't get it during class.
