This is a text about elderly people. Two persons wear makeup to look like old people and to understand what it's like to be old. after this experiment one of them said this.
They were talking about real things and I felt unqualified. I didn't have that life experience. They had been through so much. It made me realize how ignorant I was. It was as if I was seeing the young people inside them.Before I would have just seen the wrinkles.
I can't understand the meaning and what grammar this is?
