You don’t have to live with windows with bad personalities!
Admit it. It’s a problem, but never a big enough problem that ever got you past the mental paralysis caused by not being sure how to get it fixed, right?
Your windows are hard to open or close, or don’t stay open. They get stuck and you have to use increasingly strange methods you’ve invented over time, that only you know, to get them unstuck. When one of them closes, it’s not quite square, so there’s a small gap where air gets in. Or, how about that window that, when you open and let go, it slams down like a guillotine, and you breathe a sigh of relief that no one’s fingers, hand, arm, (or head?) was there at the time. It’s almost as if some of your windows have personalities, and have decided to be difficult.
