So I have a friend. He is 15 and he has a little sister who is 3. She has to go to daycare every morning before school. I am an 18 year old girl who drives. So instead of walking, I would take his little sister to daycare then bring him to school, since we go to the same school. Can I get into any legal trouble for taking them? His mom knows I take him to school sometime, but no one knows I take his sister. And his sister is his step sister, from his step dad. I feel like kidnapping could be an issue. What kind of trouble can I get in to and what ways could I avoid it?
