A man sitting in a green chair and a girl wearing a pink and purple dress giving a peace sign.
The man can't stop looking at the pretty hippy making a peace sign.
Just because a girl is  wearing a pink and purple dress giving a peace sign it does not mean she is a pretty hippy.   Just because a man is sitting in a green chair it does not mean the man can't stop looking at the girl.
