A feng shui master once told my informant that when fire and water meet within a household, conflict would arise. By fire, he refers to stoves, fireplaces, and other sources of heat, while by water he refers to faucets and pot spouts.
A few years ago, my informant lived in a house with poorly laid out kitchen, as the sink and kitchen counter each faced the stove and fireplace. Since she had a rotating faucet, the master warned her to never directly face fire and water toward each other, because it would lead to conflict. My informant really took this to heart, but her husband always dismissed her insistence on doing things exactly the way she was told to. One of the worst fights that they had had actually sparked from my informant noticing that the faucet was pointed toward the stove, which she took it as proof that her husband didn’t care if there was conflict in the family, while her husband, who prided himself on being logical, resented how she wanted him to subscribe to superstitious rituals and actively rebelled against her wishes.
This is a self-fulfilling prophecy, but it only reaffirmed my informant’s belief in feng shui.
