A few years ago, I reconnected with a high school friend (after 15 years) when I was back in my home state visiting family for the holidays. When I'm in New Jersey, I usually don't have use of a car, so whenever we go out, my friend picks me up. I haven't been to her house or met her husband or 16-year-old daughter because our routine is to go out to dinner and talk for hours, and then she brings me back to my family's house. We've talked about my coming over to her house, but when I visit it's usually for the holidays, and the logistics just haven't worked out right. And I can't just jump in the car and say "This time, you don't have to drive: I'll come to your place!" because I'm usually stuck without a car.
My question is whether I can invite her and her husband to my Boston wedding but not her daughter. I certainly don't have anything against her daughter: I simply don't know her. And there won't be anyone else even near her age at the wedding so she might be bored to tears. The next-youngest guest is about 40! But I'm thinking it might be rude not to invite her daughter.
