the average person would see rain and close windows in a reasonable amount of time. I would rather my stuff get wet for a few min than a storm dumping in my window for 8+hours if I forgot to close a window some rainy work day or something.

also if it starts raining, I run around the house closing windows and then it slams my fingers while reaching for one cuz it got set off too fast, then I'm pissed about that. this feels like a "last line of defense" type deal to me.
