back in the states

I've been back in the states for almost three weeks. i have loved seeing old friends and eating real Mexican, not our Ugandan version of Mexican food. I love that the beef here tastes the way my body thinks it should. I will forever and always love trader joes and costco. I have been bundled up since I got on the plane in Entebbe. A few days ago a friend posted a simple word on facebook "Kenya" my heart gave a little leap and I physically longed for the heat and humidity that drove me nuts so many days. Do we ever find contentment or is it in our discontent that drives us?
