I am grateful for day 1 of advent calendars. The boys were on a higher altered plane of irrational exuberant happiness.
I am grateful for Christmas decorations starting to go up in our house.
I am grateful for improvements in LED lighting. For over a century, there was pretty much just the one kind of lightbulb. Incandescent lighting was better than candles, but gobbled up many flashlight batteries over the years. LED head and tail lights just make for less to worry about when I bike home in the dark on a regular basis in these winter months.
