感想（英文）
For Your leaving
I will encourage myself,Although you are not beside me.But I still can grow up on my own feet
I want to be a cactus which stands alone in the desert.I know I am alone but not lonely.When I am down,I still can give myself a smile.
It's not about stupid or whatever
It's what I learn,to love myself more…
Thanks for coming into my life.Your indelible footprints already existed in the seashore of my heart.Although they are only a few,they are enough,the intimation between us that I have never tested before,maybe it's because we haven't really close to each other.I understand
Distance makes human perfect,but easy to break.
You are really a trustworthy person,I trust you a lot,the memory you gave me,I will keep it as an important part in the depth of my soul.You can leave heartlessly,I can learn how to be strong so that I can still carry on in the journey of my life.But what can I do this is our ending just wanna tell you when you are with me,my life is so splendid and wonderful,when I am alone without you,I will learn to live happily.

It's no use for me to be sad, you won't stay because of that.
