This has got me thinking of Texas folks who are having to improvise right now in conditions in which a long night or day without heat, power and/or water can be worrying and energy-sapping, often with no information or end in sight. Melting snow for water, working hard to keep warm in subzero temperatures, keeping animals alive, charging devices from vehicles, and so on.
Water and heat are always the critical things and so easily taken for granted especially if one already has previously undergone such an unpleasant experience. You don't know what you've got till it's gone! Many of the learning points from all this are obvious.
Never think this can't happen to you.
Never think it can't happen to you again.
The weather can do anything it wants, anywhere in the world.
Power and water can go down anywhere in the world, as well.
