I have been friends with M for more than ten years. She lives overseas and has a sister, G, who I once met for only a few hours. G is coming to visit next month and bringing her husband and child. They will be staying in the city next to us for a week. I have planned a special outing on the first weekend they arrive, and have asked them to join us for dinner on the second weekend. G mentions in her most recent email that they will come for a part of the day during the week. DH & I both work opposite hours Mon-Friday and have a small child, so I am wondering how I am supposed to entertain them during the week?
