I store my clothes in suitcases

I was thinking about this today. why do I do this? I am so aware of the temporal nature of life. Security is not much of a concern to me; in fact, I am inherently unstable, but well able to navigate through my days despite this. This is not to say that I lack a solid living situation. Quite the contrary. Still there is a whirlwind nature in the way I live.
Maybe it comes from having grown up in teepees and caravans.
