I feel like selective memory is fine but it could just be because mine is very random.  I'm quite sure that I remember everything but just have a very weird indexing system.  I will fail to remember something I'm desperately trying to remember but something vaguely, tangentially or sometimes not even related will trigger retrieval of something else.

LoL probably XD least you can honestly say you were doing the best you could with what you knew at the time :)
