I started editing the title for this thread and thought, "Third round? That doesn't sound right!" But yes, it's for real.
This week I will clean around the bedroom window. The house is finally staying warm enough that we need to install a fan to bring in cool night air. When the heat becomes unbearable later this summer, we'll switch out the fan for a small window air conditioner.
Both machines are stored on the floor of DH's closet. They will be dusty enough to need the vacuum.
