So about a week ago, I caught a cold. Nothing serious, but it's taking a while to clear. Then two days ago, I noticed I couldn't smell anything. Sinuses are still acting up, but I figure things will clear on their own. A little while ago, I'm sitting around wondering why the house is all hazy, considering that if the sinus pressure is enough to affect my vision, I should go on meds. Then I started thinking, why is that side of the house hazy and that other side not? Looked out the window. I can see fine, so it's not sinus pressure. For a few seconds, I'm wondering if it's not my water heater that's sprung a leak and I'm walking through the kitchen to get to the utility room when I realize that it's not steam, but smoke coming out of the pot of chicken soup I'd left boiling an hour or two before.
