It's a little wierd. I have late classes so all the lamps are on when I get out. Every day I walk past the same lamp post and it always goes out. It doesn't matter what time it is; if it's on it goes out. Other people walk past it and nothing happens...
Today three of the lamp posts I walked past went out, not just that one.
What's funny is I've also had incidences while I was driving down the interstate and certain lights would go out as I drove past... and always the same ones no matter the time...
