And the green grass grows all around

I've been here for about a week now - actually, exactly a week. My plane landed at 11:00pm last Thursday. I was so excited to be home - green trees, grass, blooming flowers, my bedroom, my family, my friends. It seemed to me that everything I loved was here. But...that is not so. I have also grown to love the searing heat of the Arizona desert (well, not love exactly), the intense glare of the sun, the bustle of an actual city. And now I find myself pining for Arizona the way I used to pine for Wisconsin. And whenever someone asks me what I'm doing after college, I get a sinking feeling in my chest. My answer used to be an instantaneous "Oh, I'm definitely going back home." But now the thought of trading the wild beauty of Arizona for the equally lovely if a bit more domestic Wisconsin is harder - the lines of home have blurred. If home is where the heart is, and my home is in two places, does that mean my heart is in two pieces?
