Don't be sad.
Maybe it's your mistake, maybe not.
Any way, don't be sad!
You have life and that's the happiness.
Think about your friend, who live in the hospital now.
You will be alright.
Love yourself and love everyone.
Now, make a smile and love the life.
Don't be sad,
everything will be alright!
