A young girl is laughing and chasing pigeons on the street where other people are walking nearby.
A girl in pigtails laughs as she throws bread crumbs to the pigeons.
Not all young girls have pigtails. Just because the girl is chasing pigeons does not mean she throws bread crumbs at them.
Just because she is a young girl does not mean her hair is in pigtails. Just because she's chasing pigeons does not mean she's feeding them bread crumbs.
The girl is chasing the pigeons and she doesn't necessarily throws bread crumbs just because there are birds.
