Ds’s maths tutor was meant to come round Tuesday eve for her weekly tutoring session. She didn’t come. I emailed her and rang her - phone went to answerphone. I rang her the next day and today to check she’s ok - no reply. Would I be overreacting if I rang the police to ask them to check on her? She lives alone. I don’t know her exact address. She’s generally reliable though can take a while to reply to emails. I hope she’s ok.
