According to one of my best girlfriends (who's now expecting her and her husband's 4th child), she lost blocks of memories when she was administered anesthesia for childbirth. She no longer remembers her 7th birthday, relying only on pictures to fill in the gaps. I was sure this wouldn't happen to me, as I have the memory of a steel trap, remembering things that other people would normally forget, to the point that I've often been told, "I can't believe you remember that!" Yeah, my brain is cluttered with names and faces, incidents, memories... some great, some not-so-great.
And I was right. Everything is exactly where I left it. The steel trap still works. Sometimes, much to my chagrin.
There are things in my life that I would much rather forget... things I've seen and heard that I'd rather have purged from my memory... things, incidents, people that have in the past made me plunge headlong into sadness and anger... why can't I just remember the good, the fantastic, the joyful? I know, life just isn't like that.
So I choose to conveniently forget... put away all those less-than-savory things. I've found that it takes way too much energy to dwell on old hurts.
The past is the past is the past. I leave it there, where it belongs.
