I love travelling hubs. Those points where travellers come together; the point being to fan out again reaching to the next destination.
Airports, bus depots, and train stations filled with coming and going. Big bags, small bags, suitcases and backpacks. Experienced and efficient, or first timer and unsure; all funnel through with a unified goal of catching that plane, train, bus, or ferry.
Watching people say their goodbyes is as heart wrenching as watching the hellos is heart warming. A constant ebb and flow of coming and going whose balance must be maintained.
