Hitting the head hard

Oh how, do I try to rember what I did yesterday,I have no clue. It's  because I've  hit my head hard,oh how I try to rember who we are. No clue to who I am.it's  not because I'm blonde it's  from hitten my head hard. Oh how do i try to rember her,the times I've hit my head, I don't rember who we were in the movies we made together. I just try not to hit my head when we are in bed. The Dr said one more hit could cause brain damage,would you love even more that i was brain dead from my head hard.
