Today is a very special day

Today... is the 9 week anniversary of when the guy who lives behind me turned his deck light on.

9 weeks ago today, the dude who lives behind me had a party. As is required for parties, he turned on every light in his house - including his never-used deck light. Said deck light shines right into my house. Party ended. Deck light stayed on. I didn't notice until later that week.

Hmmm, that guy hasn't shut off his deck light I thought. Bemused, I noticed all of his shutters were drawn making it nigh impossible for him to see the light was on.

Two weeks went by. I got annoyed. I thought, I should tell him his deck light is on. I'm lazy. I didn't.

Four weeks went by. I got intrigued. I wonder how long that light would last?

Six weeks went by. I am past the point of no return. I can't walk over and say - yo, dude, your deck light has been on for 6 weeks. He'd be like wtf didn't you tell me earlier.

Eight weeks went by. I was out of town, but at least I knew the constant light being on would be there when I got back. It was.

Nine weeks went by. I decide to document the light on R4NT. The picture above is not the said deck light rather a representational mock-up based on the fact I am too lazy to take a picture and upload it. I promise you, if 10 weeks goes by, I shall record the deck light for all time on the internets.

9 weeks = 63 days = 1512 hours. Assume light bulb is a conventional 60 watt light bulb. 60 watt bulb on for 1512 hours = 90,720 watt hours. 1,000 watt hours = 1 kilowatt hours (kWh). 90,720 watt hours = 90.72 kWh. Estimate a cost of $0.10/kWh. Cost of a light on for 9 weeks straight? $9.07.
