One of my friends and I have traveled together a couple of times, but I have had some pretty bad experiences with her. She is the type of person that never wants to get her hair wet, if you know what I mean, and that annoys me a bit because I love adventure and she doesn't enjoy it as much as I do.
I don't want to break her heart, but she really wants to travel with me next month, and I really don't want her to. How can I tell her nicely that I don't enjoy traveling with her without upsetting her?
