The following pasage is a piece of translation I made as a model answer for a translation test. May I ask you see it and correct mistakes if any? I'd really appreciate your help.

The memories entrenched deeply in our mind come back more easily, however hard we try to forget them.
we donít remember when they happened- we may not remember when they happened (It's not an absolute rule)
we happen to recall them even if it seems we almost forget them

and they may come back to us years later even though we hadn't given them a second thought
