We are going away for 4 nights. Au Pair is staying in our home (own choice, she could have come). She has got her boyfriend coming to stay for just over a week which includes those 4 nights. I was thinking of saying to her that I will buy some pizza, fresh pasta & sauce, milk, bread, cereal, salad etc for them, is there anything else she wants added to the list? But I don't want her to see it as I am prepared to pay all the costs of feeding boyfriend as well whilst we are not here. I feel differently about it whilst we are here the following 4 days for some reason. Would that be reasonable? Or should I provide 4 main meals for the two of them, plus staples for the 2 of them for 4 days? It seems a bit much if I do that, but want to be fair and reasonable. He was originally supposed to only be coming for a weekend/3 nights but somehow it's ended up being quite extended. I also need to set the groundwork on this occasion as she's going to be with us until summer next year so I can envisage similar situations arising again. Be grateful for any opinions.
