I can not recall all the details of all conversations and all that happens. A lot of my life gets "blackouted" after a while.
I mean yea I may can remember what I did last night _now_. But after a few days or weeks or whatever time I forget them. And it is no different than having a blackout.
Can you really remember a all connecting history without any gaps?
I bet there are always some gaps in the middle, where there is just nothing.
