Left Blinker

OK someone told my husband that one of the rear lights was out on his car so he's got me sitting at the wheel pumping the brakes so he can figure out which one. No luck there so he asked me to turn on the left turn signal (lever on left of steering wheel) and I flipped the lever on the right and turned on the wind shield wipers. My husband is flabbergasted and asked me how could I not know which lever to flip when I use the turn signal every day. Well I was reading a book and distracted but still tried female logic on him and said that this was his car not mine. That didn't fly either 'cause we drive identical 2005 Prius Hybrids (mine's gold and his is silver). At this point my husband is standing there looking at me like I've got two heads....or maybe no head. Well, I'm not usually so feather-brained and no, I'm not blond....just not too clever with auto gadgets. My sister asked me one time if I even knew where to put gas in my car. I told her I'm not stupid (just spoiled) and there's a perfectly good manual in the glove box that I could use to figure it out if I ever have to. I've been driving this car for three years now and haven't had to yet since I only need to fill up every other week and my husband takes care of it. Probably couldn't get away with this if the car didn't get 42 to 50 miles/gal around town and 60 on the highway.
