As you get older blackouts seem to come more often: You remember someone’s face but not his name. You recall situations and don’t know if they were real. You’re forgetting things you’ve done, should have done or better not should have done. That’s somehow okay if no one else is involved in that blackouts but you.
It’s not a nice situation when someone tells you “I know what you did last…”, if you know what you’ve done and it’s something ugly.
How strange would it be if you’ve done such a thing, someone else could know it, but that one isn’t you?
