How about working for a classmate? I don't know how to talk about treatment. She opened a new shop and wanted my help. ask
She invited you so warmly, if you don't have a job yet. She will take the initiative to tell you about the salary. Since we are classmates, we must be embarrassed to give too little. If she works for a month or two, you can continue to do it. If the salary is really low, you can tell her and find another job.
