Do love open windows. The top windows in my bedroom are kept open April - October, and during the warmer months the large casement window also. Normally, I have both the french windows in my through living room and the kitchen door wide open at this time of year (opened as soon as i go down in the morning. However, at present with my very new rescue cat, cannot do this. Have top windows in living room open and will have to put up with this until she is ready to be let into my garden. I also have noted how seldom my neighbours, in my very quiet Close open their windows, and began to think i was peculiar. Good to know there are others out there like me.
