Why do I have to put up with their family?

Please tell me if I am expecting too much?!?
If I have made plans with a friend to get together and go out to eat, see a movie, or perhaps just sit and talk, why is it that she sometimes wants to bring a younger family member along with us?
My friend and I usually go out once or twice a month. It is always scheduled ahead of time. We have a lot of fun and enjoy ourselves talking, laughing etc. We live about an hour apart from one another. My friend’s granddaughter lives halfway between us. They see each other a lot, and speak on the phone almost every day.
Her granddaughter is a junior in high school. I do not care for the girl. She is not very nice and I do not enjoy this girl’s company. Trust me, I have tried to get along, or be laid back, but I just don’t wish to be around her. She is sneaky and very difficult. My friend sometimes acts badly when she is around this girl. It is very frustrating!
I have said to my friend that I enjoy it when we get together…just the two of us. Things are fine for awhile, but then it always happens again.
When the girl is with us, I tend to be quiet and I don’t really enjoy talking about things that we usually do. It’s not the conversations that an eleventh grade girl needs to be in on. We talk about the news, politics, books, gossip etc. The girl has been rude and interrupts when she gets bored.
Yet even after telling my friend that I enjoy seeing HER, and if she wanted to spend that time with the girl, I would be fine with going out with her another day, she still won’t stop. A few times she has brought her along without letting me know ahead of time!
I would hate not seeing this friend. We’ve known each other for quite awhile now. I know she enjoys herself when we get together, as do I. I’ve asked her. She calls me her best friend.
I’m genuinely stumped!
Any ideas?
