As you can see, I am virtually fluent in French so no problems there 
I am assuming that we will acquire a monosyllabic 15 year old French boy to sit alongside our very own one which we already have at home. They will either barely interact or spend most of their free time playing x-box (actually, no problem with that). I also have a DD who is one year younger, and, erm, growing up, so I'm hoping we do not get a handsome, charming one to further add to the mix.
Anyone got any tips on things that have gone well/things to avoid?
