Forget the past.
Sentiment: NEGATIVE
Past is past.
I don't talk about the past.
Let the past be content with itself, for man needs forgetfulness as well as memory.
The past is what the past is.
Memories are the key not to the past, but to the future.
Never revisit the past, that's dangerous. You know, move on.
I don't care about the past.
We can't let the past be forgotten.
In this bright future you can't forget your past.
The past is what you remember, imagine you remember, convince yourself you remember, or pretend you remember.
