Who Did It?

What did you do today?
I don’t know what I did today.
I know that I am here, now.
I see that some yard work was done.
I wonder if I did that.
Maybe I did, I don’t know.

Who are your friends?
I don’t know who my friends are.
I don’t have a roster of them in my head.
If I make a mental list of them, it is being created now.
I don’t really have any friends at all. 
Sometimes someone pops into my head.
I think that might be my friend, I don’t know.

A record of people I know and things I’ve done does not exist.
There is only now.
So what have I done?
Who do I know?
