Sometimes, money can be found in places of the unknown. Any spare change found could and can be put back for a rainy day. Once, I was taken every time I spent something and got, One dollar back. Depending on how much I got back, I always put it in a golden envelope. Well, I placed it in a hidden place until the next time. SO, my tip is : No matter what it is, try to sit on it, if you aren't already...(inside the couch).
