"When can you come for dinner?"

So as many of you know, Emily and I moved to American Fork in a little townhome back in July. We started going to the ward a few weeks before we moved in. It seemed like a real nice ward from our first impressions. We also noticed that there weren't too many people that were our ages. It seemed that most of the ward members were in their early 30s to their mid-40s. After about a month there we were called to be Primary Teachers for the 8-10 year olds. We have found that once you get called to the Primary, you really don't get to know to many adults in the ward, but we know every primary child that are the ages of 8-11. Having said all that leads me to my story. Emily and I have our certain Sacrament Meeting spot. (It seems that in the Mormon Culture, if you set in the same seats for two consecutive Sundays, you basically claim those seats as yours every Sunday.)
Anyway, Emily and I claimed the first row of the overflow. (Yes they are hard seats, but it gives you so much leg room.) Last Sunday, we ventured out and decided to set in a different spot, and we arrived about 5 minutes early. As we were waiting for Sacrament to start, a couple, probably in their early 30s, sat in the pew in front of us. The only thing that we knew about this couple was the guy is the Executive Secretary in the Bishopric, and the only communication that we had ever had was when Curtis, the guy, asked us to say the opening and closing prayer for Sacrament awhile back, and if we had signed up for tithing settlement back in December. In fact, I don't think we have every formally introduced ourselves either.
Here comes the meat of the story. Seconds after we said Amen to the closing prayer, Curtis turns around, and asked "What day can you guys come over for dinner this week?" Both Emily and I were a little taken back from that question for two reasons. One, we had seriously never introduced ourselves! We had no idea what the wife's name was, and they only reason I knew his name was because it is always on the Sacrament program to make appointments with the bishop. Second, there was no intro to the question like, "How are you guys?"; or "How do you like the ward so far?"; or "We are Curtis and Krystal Read, and we would like to have you two over for dinner sometime?" Just, "What day can you guys come over for dinner?" We decided on Wednesday at 7:45, and as Emily and I were walking to our class, we both looked at each other and said, "Well, I guess we have a date this Wednesday with people we don't even know." We actually went searching for a ward list after church to find out what their names were. Anyway, we went to dinner on Wed., and we got to know a couple more people in the ward.
