Boy in backpack crossing the street, Other people, all Asian, are all in crosswalk walking towards the boy.
The boy is on his way home from school.
I can not infer that just because the boy is wearing a backpack he is way home from school.
Just because a boy is crossing a street does not mean he is going home from school.
The boy could be on his way to school instead of from school; we don't know in which direction he is crossing the street in relation to his school. Also he can be wearing his backpack for fashion and not specifically for school.
