I'm the same way when I hear my son in there running water as he shaves...WHY the running water???

My Dad used to shave in a basin of water just fine.
We also have water saver shower heads that one can turn off in between getting wet, soaping up and rinsing, which Mother and I do....but can't seem to convince visiting kids and spouses to do the same. They are used to living in town and using water like it's going out of style...you'd think if you were paying for every gallon you'd be more aware of water usage, wouldn't you?
It's not that we are afraid of the well running dry...this well flows between two layers of flint rock and runs 80 gal. to the hour, but it's just the thought of wasting all that good water...why do it?
