Right? She'd be like the 3rd hillbilly cousin that you're stuck with for the summer, and you have to keep arranging dates for her so you can go out with your boyfriend. How many nice ways are there to say "Well, let's just say she sleeps in the yard and has a helluva howl and really really likes coon hunting"!
