They could either be memories you would want or never want to forget but what can you do? What's there is there, no matter how much you want to avoid it, you would always be reminded by these certain things. It's how you interpret these memories in the end that would show who you really are. I mean, you could always try to avoid it or change your views of it and just learn not to make the same mistake twice or let it haunt you and be afraid of it.
