I turn on my headlight and both rear blinkies when I leave work at night - around 4:30. I'm with you, I don't wanna have to deal with trying to turn everything on once I'm riding. My commute home is 80% bike trails but I use the lights anyway for the streets I have to cross and to make sure I can be seen by anything on the trails and to see.
Maybe just a simple "thanks" the next time he tells you to turn it off will eventually shut him up!
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
