He's just turned 15, girlfriend is nearly 16. Holiday arranged via his dad (my ex) and her parents despite the fact he lives with me. School grades are atrocious, no effort and a load of attitude which means there's not a lot to reward with a holiday. Literally just been furnished with the details that his dad signed off the week from start of Yr11 as ok - 'he'll pay the fine if there is one, just tell them he's ill!' plus the second blow that son will be sharing a bedroom with the girlfriend - her parents don't see an issue with it. So my conundrum, does he go, or do I play wicked parent and withold his passport?? My gut says the latter as I don't know these people. Thoughts please
