<human>: Give me the gist of the text in a nutshell

This is mainly posted because of something that came up as a teacher that I can see happening again - but I'd also like to hear your experiences, and of course, I'd really appreciate some advice

I cut myself on and off for about ten years and I'm now training to be a teacher. When I taught last year, a pupil asked me what my scars were from and I didn't know what to say. I am of the opinion that you should be honest with children - and I've no problem with sharing to - but I'm not sure that it's entirely appropriate in the classroom. I'm working in a school very soon and I'm sure it will come up again. My clothes generally cover them but, e.g., my jacket rides up if I'm reaching for something.

If it happens again, or if it were to happen to you, what would be an appropriate answer?
<bot>: should I be honest with my pupils if they ask about my self harm scars? And have you been in a situation where you've had to bring your own honesty into question?
