Have you ever have such feeling? I had it many times!!
If this is about work, you can still get a new job and forget the mistake.
What if this is from the person who u care most?
You will feel sad definitely and wordless because you can’t do anything on it.Come on…these are past tense…. :(

When I try to think on another side >> Is there any mistake/past my friends or colleagues did which I still remember until now?
To be honest, the answer is YES.
I used to forget things fast especially sad one.If I keep remembering the sad incident that means it is serious one.

Anyway I would still say everyone have diferent perception on the “mistake” and “past”.
Maybe he/she think the mistake/past is kind of serious wherelse I think another way round.
OR
Maybe i thinnk the mistake I did or my past is just nothing then I would just get angry to myself…Why he/she just can’t let go?Why I did such mistake? Why I am so stupid last time?
Do I have to CRY?

OR beg for forgiveness and forgetness??

In the end, I still can’t do anything because I can’t control human thinking….

=.=” … oh shit!!!now I think all these are just nonsense… “FAI WAH”!!! :(
