premise: A man in a park is leaning on a bar looking, towards the camera while a boy in the background is leaning over a bar, and a lady with a bag is reaching towards a girl. hypothesis: A dad watches his son play on the bars, while a mom takes her daughters hand at the park.
neutral: A man watching a boy does not mean they are dad and son.  The son may be leaning on the bars, but he may not be playing. A lady reaching for a girl does not mean it is a  mom and a daughter.  It also does not mean she is trying to take the daughter's hand.
