The mother

I watched them stepping through the door
She and her son first, close to each other. He was behind, someway detached from them.
She looked around and then sat on the bench with the child close to her
He decided to stand still, alone
There was a good light, the child kept buzzing around, the man was leaning against the wall 
She was silent and confident
I watched the scene for a while, then move to her asking the permission for a picture 
She looked at me, then smiled and nodded before turning back to her own thoughts
