A key left
But the lock is waiting him
To come back
After a while
The key came back to the lock
But he found that
He can't fit in the lock anymore
Because she is rusted
A heart is like a key
Once it is rusted
The more you get close to that person
And trying to fit yourself in
You will found that
You can't go back to the past
No matter it is
A relationship,
A friendship,
Or in a family,
Don't do something
That will hurts each others
You can never go back
To the past.
