This really seems odd to me. I can't think why anyone would run off with a 15yr old, teacher or no teacher. If the pair of them are 15 then hey..,, you could kind of understand but then they’d get no further than the ferry terminal I guess. But this blokes a (cough) responsible adult and she’s so clearly a minor.
I'm not waiting to hear the facts, the Mans an idiot pure and simple. No excuses on this one. I feel for her mind, she must be going through all sorts of mixed emotions and messages. And no doubt too frightened to come home, poor kid. He, well in true STW style should MTFU and contact the authorities now and do the honourable thing.
Having said all that my Sister had an affair with our Drama teacher and he got the sack there and then, my Sister ran away from home, took us 14mths to find her, turned out she went to That London and ended up in a Convent.
