DD goes on school camp soon. All the pupils going got to write down 1 friend that they wanted to be in a cabin with. When we first put their names down for camp, DD's friend (M)'s mum said it would be good if our DDs put each other's names down and I said I'm sure they would as they are close friends. However another girl (K) is going who is also a good friend of DD and probably has more in common with her and would probably have a better time sharing a cabin with. K & my DD decided to put each other's names down but not to tell M so as not to upset her. M assumed that DD would be putting down her name. Now M's mum (who is also a friend of mine) has found out - she's not angry but it may be that M is paired up with one of the unpopular girls in the class and I'd feel really bad if her experience of camp is ruined because of this. I haven't denied or confirmed whose name DD put down but I don't want to lie but how do I say that DD put down K's name as they felt they'd get on better sharing a cabin? I could ask that the 3 of them share a cabin with someone else as well as this could be possible but I feel one of them will be left out. How to handle it? Thanks
