U is a tough letter. I only had two ideas listed under U last year: unplug and upside down. Earlier this year I performed the "upside down" act by building this snow person. I saw a grown man walk by, do a double take, and smile. Mission accomplished!
Since there's no snow (thankfully) left and I already performed the "upside down" act, the only one left was unplug. Before bed tonight, I unplugged all of the electronics, lamps, phone chargers, etc. that we leave plugged in all the time. I'll save a little power tonight and do the environment a small kindness.
