My MIL wants to throw me a baby shower, and has asked me to get a list together of people I'd like to invite. I recently moved out of state, and haven't kept in touch with a whole lot of people since I graduated from college in May, but certain ones still talk to me a lot through facebook, and have expressed interest when I post pregnancy/baby-related things. My list right now only has about 13 people, which I know is small, but I don't want to invite people who I haven't kept in touch with for months and months. I want to invite the people who ask questions and comment and seem genuinely interested in my pregnancy and the baby. I have a group of 3 friends I've known since pre-school, and whenever we've gotten together in the past, it's always been all of us. However, one girl and I haven't spoken in years. We have no hostility or negativity between us, we just aren't in touch. However, she's the sister of one of the other girls, who I DO keep in touch with and has expressed interest in the baby. Would it be rude to invite the friend and sister I still talk to, and leave out the sister who I'm not in touch with? Or would it be rude to invite the sister I don't talk to and make her feel obligated to come or send a gift? What is the etiquette in this situation?
