People always regret for something. Regret for not choosing another choice he/she didn't choose at that time. Sometimes even though they know that what they decided was the best and only choice, they still regret. Perhaps they just expect something that never happen. I don't know.
pathetically, I am one of them.
Maybe, these thoughts come to my mind just because I am sleepless and insomnious rightnow. I also have no idea about this.
p.s. the pic is found accidentally when I googled for pics with the word "囈語". I found I am fimilar with the phrase. And then after googling for a while I found this phrase is 席慕容's handwriting for her peotry, "一顆開花的樹".
