Good job cutting down on your water usage! I always do the same. It is especially important not to waste faucet water that has been cleaned and treated.
I think that this video is a great demonstration of how everyone should brush their teeth! I think that your water usage was very appropriate and not wasteful at all. Water waste is an important problem in America. Good job!
