E equals Empty!

I use to love when the kids used my car for any reason and brought it home with the gas gauge on "E."  I don't know how many times I told them "E equals Empty, not enough."  Bobby was my worst culprit.  I don't know how many times I looked at the gas gauge and it was on E.  Finally I told him, "If you run out of gas push the car home.  I refuse to get you."  Of course he always called me anyway, and yes I always bailed him out.  I always put gas in my car when it is on half a tank and do encourage them to do the same.  Now the gas gauges shine an idiot lite to tell you you are almost out of gas.  Stacy knows exactally how many miles she can go on that light.  Still to this day I get the call, "My light is on.  I'm almost out of gas.  Come and get me if I don't get home."  It's not my car!  Help me, I want to run away.....
