we have invited dd's best mate to come on holiday with us for a few days , we are staying in a cottage. Taking the other girl won't cost us anything because we've paid for the cottage anyway and she will have spare bed in dd's room. We won't be doing activities or at least not anything we have to pay for. If the girl's mum asks us if she can pay us anything, or just gives us some money, what should we do? A little extra would be welcome, but then again we don't want to seem money-grabbing . What SHOULD we do? I'd like to avoid an embarrassing scene with us saying 'oh no it's alright' and her saying 'oh yes I insist' and then if she does insist are we supposed to give in. or not? And then how much is right, and how much is too much?? Help!
