Something happened to the window in the night and I would like it on record that I noticed immediately. Before she was even properly awake. Before the coffee. I was the first one in the house to understand that the glass had changed.
It wasn’t broken, exactly. I want to be precise about this because precision matters when reporting a crisis. The bottom third of the pane had gone cloudy, a pale, smeared, milk-colored cloudy, like something had breathed on it from the outside and never stopped. I put my nose to it the way I always do to check on the morning, and instead of the cold clean smell of outside air coming through the little gap at the frame, there was just glass. Fogged, strange, unreadable glass. I sat back and looked at it the way you look at something that used to be fine and no longer is.
My first assumption, and I stand by the reasoning even if the conclusion was wrong, was that the window was sick. It had a sheen to it I didn’t like, a kind of soft gray film, and when I touched one claw to the glass very carefully, not pressing, just testing, the whole patch smeared sideways under my paw like it wasn’t solid at all. I pulled back fast. A window that doesn’t behave like a window is not a small thing to discover alone at that hour.
I patrolled the sill for a while, looking for whatever had done this to the glass, some kind of residue or stain or evidence of an intruder who had come in the night and left its mark and gone again. There was nothing. No smell beyond the ordinary cold-morning smell of the sill itself, no sign anything had been there at all, which made it worse, not better, because it meant the window had simply done this to itself.
She found me sitting guard in front of it when she came in with her mug, the steam off it rising in a way it only does on the coldest mornings, and I made sure she understood the severity by not moving, by staying planted exactly between her and the affected area as if my body alone could contain whatever this was. She didn’t seem alarmed. She crouched down next to me holding the mug with both hands and looked at the glass the same way she looks at most things that don’t actually worry her, which is to say not very hard, and then she breathed out, slow, right near the bottom corner, and the cloudy patch spread wider and thicker right in front of us.
She was making it worse. On purpose. I watched her do it a second time, deliberately, her breath going out long and warm, and the fog bloomed out across more of the glass than before, and I understood then that whatever was happening to the window, she was somehow part of the cause of it, which did not make me feel better about anything.
Then she lifted one finger and dragged it slowly through the fog, and a clean streak of window appeared behind it, sharp and clear, outside visible through it like a little window within the window. She did it again, a curve this time, something round. I put my paw up against the glass where she’d touched it, not understanding yet, and found it was warmer where her finger had been, and cold everywhere else, and the fog was already creeping back in behind her mark, erasing the clean streak like it had never happened.
I sat with that information for a minute. Then, because I am thorough and do not leave a threat unverified simply because a larger and calmer party has declared it harmless, I leaned in close to the glass myself and breathed out hard through my nose the way I do when I’m annoyed, and a small patch of fog bloomed right where my breath hit, exactly like hers had, exactly the same gray softness.
So it was me as well. I had apparently been doing this very thing every cold morning for some time without noticing, breathing on the glass and fogging it and never once realizing the fog was coming from inside me and not from some failure in the window itself. This was, I will admit, a difficult piece of information to sit with first thing in the day.
She finished her coffee standing right there, one hand resting on my back the whole time, and every so often she’d breathe out near the glass again just to watch the fog spread and then wipe a shape into it with her sleeve, a loose circle, a line through it, gone again within a minute as the room warmed. I watched the whole cycle happen four or five times, cloud and clear and cloud again, and each time I checked my own reflection involvement by breathing hard at the exact spot, and each time it worked, which I found less reassuring than she seemed to think it should be.
By the time the sun came all the way up over the yard the glass had cleared on its own and stayed clear, ordinary and transparent the way it’s supposed to be, the cold gap at the frame letting its usual thin draft through for me to put my nose into. I checked it twice more before noon just to be sure it would hold. It held. But I know now what that window is capable of doing to itself in the dark with no warning, and I intend to keep a closer watch on it than I used to, especially on the coldest mornings, when I have reason to believe it might start again.
