I was the assistance to someone.
They did not need any help.
A young person is riding a bicycle.
The man is rubbing a tree.
A classical piano plays softly.
Two girls cleaning glass while a woman speaks to them.
A man is in the water.
When she moved, my sister took with her an item my father didn't use.
