I am small. have short hair and am easily bored so my showering is well under eight minutes, probably nearer four to five with washing and rinsing all in.
On the other hand, my DH is the ultimate bathroom slowcoach and I have to bite my tongue at the ten minutes he actually spends under the shower and the forty minutes it takes for him to complete his ablutons and grooming in the morning.
However, I realise that this is part of his ritual 'awakening' and donning his psychological armor to face another day at work and I am as tolerant as I can be.
A recent postal announcement declaring that we will be fitted with a compulory water meter in the next couple of years might well dent my tolerance, however!
As for forty-five minutes in the shower. If I hadn't read it I would not have believed it possible. What does it cost? What about the other people waiting for the bathroom?
