Have seen some sights after being in the game for over 15 years.
I think the best was a lady in labour, I rung door bell as usual and carried on cleaning windows, I never wait for customers to answer door cause sometimes they take ages or don't bother at all,went up ladder on to flat roof at front of house and started to clean the 1st window I come to, all I heard was shut the curtains its the window cleaner, of cause you then look to were the voices came from. All I see is lady on bed, legs wide open, and midwife in action, what a sight. This was years ago and I still clean their windows and they still joke about it.
The kid must be about 12 years old now and the dad jokes we should of called him Darren after me. If they never shouted shut the curtains I would never of known anyone was in the room .
