I wonder if home means something else to people who travel a lot. Is it something more special because they have limited access to it? Do they find it easier to make a place their home or harder? I sometimes find it easy to be at home almost anywhere, but I wonder if it has got to do with having stayed in a single spot for many years and it feels like you can relax and make yourself comfortable anywhere because on some instinctual level you know that abode is only temporary.
Which begs the question.
