"Superstitions"

One superstition I used to believe was that if you whistled at night it would bring evil spirits, so I would never whistle at night for a long time. Another one is if you see a white owl that means someone was dead or going to die. The first superstition I heard from my mom, and she heard it from her mom which probably was told to her by an older brother or someone trying to scare her, I don't know. The second superstition was supposed to be what some natives believe, and I believed it too for a while because the night my cousin died my brother said he had seen a white owl that night. I know now that those were exactly what they were "SUPERSTITIONS'.
