hi , would you please help me about this question ''write a reflective account dealing an occation whn you have had to deal wih inappropriate or unwanted behaviour''

as unfortunately I got my DBS check too late and now after 2 months from opening schools I want to start my training as teacher assistant this week in school, I don't have any idea about this question. would you please help me about this question, if you have any experience about inappropriate behaviour in school?
