At a college open evening a potential student asked about Italian classes. The college didn’t offer this language but an Italian, part-time teacher colleague of yours overheard the request and told him that she gave private Italian lessons on her days off. Pleased, he asked for her mobile number which you saw her give him. A few weeks later you met him in the corridor and he told you he was studying for ‘A’ levels in the college now. He still wants to learn Italian but has lost your colleague’s mobile number and asks you for it. You know the Italian teacher is desperately looking for more work. Should you give him the number?
