not quite sick, but not quite well either

The title here describes my current circumstances, and Leah's too. She thinks we might be getting poisoned by some sort of gas, so we opened all the windows for a couple hours this evening. Strangely, it didn't get that cold in here; it must be that alot of heat comes up from downstairs, or that our air circulation isn't so good in here. Now that I think about it, though, I believe it may be the former: I recall in the fall we didn't have to turn our heat on nearly as much as I had expected. That's happy news, if we're able to take advantage of the effect now that it's getting on towards spring, because they've been killing us with the oil prices this year! Our new house has gas. I wonder how that's going lately?
