parting is such sweet sorrow

has anyone ever seen the hugh grant movie "love actually"? remember the scene at the airport when he talks about how love is all around you there when you stop and take notice? so many people saying goodbye and so many people saying hello and lots of laughter and lots of tears.
I noticed this was true as I dropped off  a loved one yesterday morning.
it's not easy saying goodbye to someone you love, especially when they are traveling far away. but if you're lucky, you get to welcome them back.
