I'll see you again.

Is just difficult to express the feeling of saying good bye and accept the fact that there is not date to meet that person again, and you just have to live with the doubt of one day you will see that person again.
I wasn't ready to say good bye .. I just could say I'm going to do the best to meet you somewhere around.
You love for real when you love the imperfections of that person and is what you miss the most
