What is the difference in meaning between ...

Hi Knoff,

Thank you for your explanations. I totally had the different meaning in mind.

When I was little my mom would take us to meet the "school bus". My younger sisters had morning classes (different schools, different pick up point), and I had classes in the afternoon, my brother had pre-school. She would have to go out and come back to get every one of us to meet the "
