I'm not far behind i'm 30, but I grew up with A/C from like april through nov. my dad hates the heat. I ended up being the same way. i can't even drive with the windows down in my car on hot days unless it's a weekend and I'm going someplace to just hang out. During the week when i'm working I can't do it. Not to mention driving with the windows down is no more efficient on the gas mileage then using the ac.
I look at it as a comfort and convenience thing. why should I sweat when i can click on the little white box and walk into a nice cool house. Like I said before gas is very expensive but the actual use of electricity isn't so until it gets cold out an the fiance complains about it being too cold I'm running the ac as much as I can.
I guess I'm one of those scary people who can't live without it.
