How can I be safe at night when I'm coming home from school? Please see details.

I recently got a job (yay!) and I’m doing a tonne of training this week so that I can get done quickly. Tomorrow, for instance, I’ll work from 3:30 to 7pm, then the same on Thursday and Friday, and then working all day on Saturday and Sunday.

Unfortunately, my mom is seriously paranoid about me being out at night, which, while something I worry about, isn’t that big of a deal to me. Call me crazy.

What are some things I can do so that my mom sees that I’m making an effort to be safe at night?
