Background 1: Tonight we had a special service at church. Usually, nothing is happening on Sunday evenings, and we usually attend the Saturday evening service.
Background 2: Elizabeth knows what church is, and knows what it means to go to church.
Well, Elizabeth is used to having people over after we come home from church in the evening. So, she was asking if various people were coming over tonight: Izzy, Becca, Robb (friends of ours), Chana (a good friend and a girl she plays with at church), and some others. We answered to the negative each time. This was then followed by the question: "Is church coming over tonight?" Fitting 400 people in our apartment would have been quite the feat.
