Being met _inside_ the airport by someone who cares about me. I could power a small city with the wattage of the smile that would bring to my face!
I think it comes from being a little kid and going with my mom and my kid sister to pick up my dad at the airport when he'd come home from business trips. He was always so happy to see us and I think that imprinted on me somehow. It doesn't happen that often for me, but I'm hoping maybe this weekend it could be a birthday present...I doubt it, though.
