A little girl is on a playground swing while a redheaded man in a green sweatshirt stands by.
A girl is being watched by her father while she's on the swing, because he doesn't want her to get hurt.
Standing by is not necessarily watching. A man with a kid is not always a father. Standing by is not always because he doesn't want her to get hurt.
