Those Packing-A-Suitcase Blues

I'm off to Germany this afternoon. I'll be gone a week, attending and speaking at a conference in Frankfurt.
And I've got the blues, the way I always do when it comes time to pack a suitcase. I'm not sure why this happens. Once I get on the road, I'm rarely blue. It's just the preparation to leave home and family that gets me down. I don't remember it always being this way -- back when we were living in England and before that in Florida, I always enjoyed travelling. Maybe I've just had my fill of travel without my family.
Anyway, I've got to do it. I'm not financially independent, and I'm lucky enough to have a job that pays well and is relatively painless.
But I sure am blue.
