Aloha Tim3001,
1. Thank you.
2. There should not be a problem with the ceramic, enclosed water holder.
3. Choose your battles wisely, boarder. Going in with a "Feng Shui says this" Isn't going to cut the mustard unless the other is enrolled in the course as well. Otherwise they're finding their being held to the rules of an unknown game they didn't agree to play.
With commitment comes a joined perspective and focus to truly establish goals and set up the environment to mutually reflect you both as a unit. To let go of how things have been , some have had to move into a new place. Hopefully, that will not need to be the case here.
Much Love, Shawn
