Same as above comments.
In line with abovr thread. I had a customer who sadly died just days before reaching 101, sweet old lass. She just used to sit in her rocking chair by the window, thankfully her son lived just opposite side of road. But i used to wait to see signs of her breathing before i cleaned the windows, dreaded time of doing her windows every month (she was a regular customer for 14yrs). Even when i saw signs of her breathing i used to tap on windows gently so she wouldnt wake suddenly and have an heart attack.
