I thought I was being frugal and green

It turns out I was just being wasteful.
I grew up washing dishes by hand. To this day, my mom doesn’t own a dishwasher. So, it’s always dish washing by hand. My husband, on the other hand, has always been for using the dishwasher. We even got a dish set for 8, so we could have enough plates to carry us until the next dishwasher load. But I kept washing as most of the dishes as I could by hand.
After wondering for a few months which way was actually more frugal and greener, I found out today that a dishwasher uses less water than I do when I do the dishes and probably less energy as well as I use a bit of warm water.
It turns out I have been creating more work for myself for no good reason. Besides, I was getting sick of washing dishes sideways since my big ole belly kept getting on the way.
