I have an old friend, we go way back, now living abroad. Thing is, she keeps inviting herself to stay! It's always nice to see her, but I'm beginning to think she's using us as a free hotel. The visits are getting more frequent and now she's said she's coming in August with her 2 teenagers! DH is getting annoyed about it as you can imagine.I don't want to lie and say it's not convenient and I don't want to fall out with her, but how can I tell her that I think it's getting a bit much?
