Useful Reflection

The tiny, green peace sign you can see reflected in our neighbor's glass storm door is fun to see, but it's in the window to the left that we find a useful reflection, and that still gives us a bit of a thrill. It's not shown in this picture, sorry, but I'll tell you about it anyway: We still find it mighty clever to be able to warm up our car from inside the house. We can't see the car when we are inside, but its taillights get reflected (in that living room window right opposite our driveway) when we click the key fob five minutes or so before heading out to drive away. There's a list of things to remember before heading out: phone, glasses, shopping bag, gloves - any number of things, but all it takes is a glance at the neighbor's window to let us know whether we remembered to warm up the car.
When it gets hot, we plan to do the same to cool off the car pretty cool?
