Dave,
I had soneone come over to me this week and said they would like me to clean there windows,
They were watching me from over the road, and I have taken over 30min to clean this house.
She has a window cleaner that just takes 10mins,
She also said they all watch you,
I think it is a bit of a mind game, if I finish to quack I do something in the van or just wipe down more
