A woman is holding her child while a man is reading something from a piece of paper and taking something from a bowl that a younger girl is holding in a park with a small lake in the background.
The people are on a family picnic.
There is no mention of eating food outdoors or having a picnic.
Not all groups of people that gather together are part of a family.
Only because a group of people are sitting in a park and hanging out doesn't necessarily mean the people are on a family picnic.
