My dd's school is organising an exchange trip to France and one of my dd's friends is going to take part. They go over there and then the French pupils come over here. We've done it before and we know that no-one checks up on your home or who you are - I guess they just trust you.
My dd's friend lives with an assortment of animals. They line the walls of her house - spiders, lizards, snakes, scorpions, dogs, cats, hamsters, fish, etc. Her home is full of animals and it's not very clean either. My dd had a sleepover there once and told me that she felt uncomfortable and slightly scared of the dad who was quite sweary and shouty. She's always refused subsequent sleepovers.
So, knowing that this child wants to be part of the exchange and that a French girl may have to spend a week with them - do I tell the school my concerns or is it none of my business? I just feel for a child a long way from home, who has no idea about the kind of place they are staying in and the school may have no idea either.
