I don't know how many decades I have in my life, but you have occupied all of them.
We cried, laughed, and quarreled, got together when we were apart, quarreled and made up again.
Finally we can never see each other again.
I thought that when we meet again, I can tell you how much I have missed you over the years, but when we actually meet, all I can do is feel helpless.
I miss you.
I like you.
I love you.
You don't need to know, and you don't have to know.
Goodbye.
