We've lived in the same house for about twelve years now. We're a family of five. It's my father, mother, my two sisters and I.
My dad's a big time money saver, he loves saving his money. He puts his money in envelopes and organizes it by 100s, 50s, and 20s. And he counts the amount of money in each envelope and writes it on the envelope. He counts it, my mom counts it, and I count it just to be sure of the amount. He seals them shut, and he used to just keep the envelopes of money in his dresser. BUT then when he needed money, he opened his envelope of 100s and there was $200 missing! Now let me be clear, the envelope was still sealed shut, never open, but the money was missing. So my dad just thought one of us kids was stealing his money. Even though the envelope wasn't open!
Now maybe another six months passed, and he opened a envelope and more money was missing. Envelope was NEVER opened, we counted the money, and only the 100s go missing.
It's been five years and money still goes missing. My dad eventually started putting the envelopes of money in a box with a lock on it inside of his closet, and the only key for the lock is on his car keys. So when my dad needed money again he got the envelope, opened it up, counted it, and more money was missing! And again it's only 100s that go missing.
We don't know the cause. We've seen stuff in our house, heard stuff, had our own experiences, and there's this story of our houses being built over an Indian cemetery, but we just don't know for certain what it is. The money just disappears, it's gone, and we never see it again. We've lost more than a couple thousand by this.
