You don't say what her hours will be. Place opens at 7pm and she will be walking through town at 10pm. Is that GOING to the job or RETURNING from it?
Does she never go to town with friends in the evenings? How has she managed up to now.
2 of my children worked and lived away from home when they were 16. As long as she is sensible and wears flat shoes when on the journey, she should be fine.
Taking an evening job has it's risks (re travel at night, especially in winter) but she must know that.
What were the first ever records that you bought and when?
Parents-in-Law. What do/did you call them?
