I think I am the only person I ever met who can intentionally choose to forget a memory. I do it all the time, when I want to forget something that is unpleasant I can just forget it... I cant remember a specific instance mind you, but I'm sure I've done it :)

@freemo repressed memories? Isn't that supposed to be bad because they'll cause weird behavior later? (of course, if they are truly erased rather than masked, it shouldn't be a problem)
