I hosted two 19 year-old college students from Tokyo this past weekend, and I will see them again before they leave (they will be here for 3 weeks, and have only spent 1 weekend with me). I thought I ought to get them some presents before they go, but I'm not sure what I should get them. Any ideas? Because they're young women, it might be fun to get them something a little more trendy, but I'm not sure what. Any suggestions would be greatly appreciated .
