The bedroom and bathroom windows are pretty old and probably different from what most of us have at home. They are heavy and slam easily. Please make sure that the push pins are in place to hold the windows up when you open them. The windows also drop very easily, so take extra care when you are opening and closing them. The fans do a nice job of keeping the windows up also.
Thunderstorms pop up frequently and quickly, so please close all of the windows while you are away.
