My bathroom is a Time Dilation Field
It only works after a complicated combination of taps are turned on and off. When you use the cold water in the basin first and then use the shower and go back to the basin, it activates a slowing down of time within a localised field. You might think that I have gone totally nuts. You might believe that I have officially lost my marbles. However, I am certain that this is the only logical explanation for my observations.
My bathroom is a Time Dilation Field and that's that.
