Two girls are walking along the street and talking.
Twee meisjes lopen over straat en praten.
The two girls that were walking together were talking about school
De twee meisjes die samen liepen hadden het over school.
Just that two girls are walking along on the street and talking doesn't imply they are talking about school.
Alleen dat twee meisjes op straat lopen en praten betekent niet dat ze over school praten.
