It's beyond me.
Sometimes I lose my train of thought.
I can't make heads or tails of it.
It's on the tip of my tongue.
Her stories stick in my mind.
UNDERSTANDING
You have to come to grips with it.
I don't know off the top of my head.
Nothing comes to mind.
You want to get something out of it.
We have to learn it by heart.
REMEMBERING
I don't see the point of it.
It's hard to get your head around it.
