I don't know what to write... Help please?

Write about a girl's first day at a new school in a new town in a new country, who decided to go for a fairly long walk into town and got lost trying to find her way back. She may or may not have friends who set off with her. She has no money for a cab, and doesn't know the exact address of the school, only what it is called. Explore the different options she might have in finding her way back, and write about how she makes her way back to her school.
