When you move near the ocean you know to expect stormy seasons and possible hurricanes, even flooding.

When you move near a dessert you expect to tolerate high heats, dry climates, and a higher risk of fire.

When you move to the mountains its mudslides, snow, and forrest fires.

And when you love a human being, esp one already aware of their limits (disabled), you listen to them and expect them to be different, maybe even hard to be around sometimes.
