It is a beautiful day outside today in NC and it’s like 70 degrees! My crocus is blooming, buttercup greenery is sprouting up like crazy and my thorn-bush (aka flowering quince) has beautiful red buds all over it and I’m sick! Bummer….not fair. In protest, we have opened a couple of windows in the house. I know it’s really old-fashioned, and probably not the right thing to do. But, I have this thing about airing out the house. It just makes it feel fresh and clean and I imagine the germs floating out the window. Silly right? Of course, it usually means the pollen floats in, but I can take a Claritin for that, right? 
I agree. There is something about opening the windows on days like this that just makes the house seem cleaner.
