Growing up there were a couple of religions in our house. My aunt was Buddhist. My sisters were Wiccan. My Mom dabbled in Catholicism and Santeria. I was flirting with Judaism. But my mother ruled the house so it was her way or the highway (I know this because one time she locked me out of the house in the middle of winter...near a highway).
So my mother had an altar which gave me the heeby jeebies. She put fruit sacrifices out to rot on the altar in devotion to the saints. When we were out of food, I gazed at the fruit in desperation. My sister went one better, snatched the fruit and got slapped for it.
My mother made us wear our underwear inside out to protect us from evil spirits. She made us wear azabaches around our necks to protect us from the evil eye. But one of her favorite things to do was to cleanse the apartment.
