Just had my dd's confirmation party last Sunday. It was very similar to her first communion and christening parties. We invite the family, some very close friend who have known her since she was born, and see her often. Then, I invited some friends from church...my friends in choir and on altar guild, dd's sponsor's, and a few others. Dd did invite a couple of her friends though. And we invited our rector and his wife. They had another party to go to, so came to ours last (got to stay longer that way!!)
We had...stuffed shells/sauce/meatballs, chicken/brocolli/pasta (ordered that), finger sandwiches and small deli sandwiches (ordered those also), spinach salad, pasta salad, tossed salad, rolls. And a cake. We did have some beer and wine but not a lot. People came and went over a period of 3 or so hours.
I like having family and friends into the house for these type of occasions. It allows my dd to practice being a hostess, and how to deal with people in that kind of a setting. She had a ball, and loved the party.
I sometimes think that people that invite a ton of people are looking for more gifts. Someone actually asked me how many people I was inviting...told them about 30. They asked me why so few....how did I expect my dd to increase her savings account with only 30 people invited!!! Tacky, just incredibly tacky and rude. We invite people because we want them there to celebrate with us. Only 2 or 3 people could actually get to the confirmation service because it was so early...so having everyone else to the house for lunch was a great way to include them.
