What do you miss most from home?

Living more than ten thousand miles away from home is really exciting, but it can be tough sometimes. What do you miss most from home? I'm not going to lie about it, but I miss my dog. He's living with my parents, and when I come home to visit, he gets so, so excited. I feel really bad when I have to leave, because it's going to be a long time until I see him again...
