You don't know happiness when it's done,
You don't know sorrow when it's gone,
And all the things that should live within your heart,
You let them part,
You let them part,
They're your experiences,
They're your life,
They're your memories and should live inside,
Instead trying to forget them all,
You should keep them, and let them grow,
They're the things that make you you and you should fall on them when you don't know what to do,
You don't know happiness when it's done,
You don't know sorrow when it's gone,
And all the things that should live within your heart,
You let them part,
You let them part,
Even when your memories are trying hard to survive,
And all you want to do is forget them and hide,
They're part of you,
Don't erase history,
Keep them with you,
No one wants mysteries,
Why would you want to forget all the good times we had running round?
All those summers climbing trees and all the cool things we found,
You don't know happiness when it's done,
You don't know sorrow when it's gone,
And all the things that should live within your heart,
You let them part,
You let them part.
You don't know sorrow when it's gone,
You don't know happiness when it's done,
They're those things no one should live without,
Without a doubt,
They're what makes you you,
Never forget,
They're a part of you,
Keep them close,
Keep them close to you,
You don't know happiness when it's done,
You don't know sorrow when it's gone,
And all the things that should live within your heart,
You let them part,
You let them part.
