The sound of flowing water. That's probably one of my and my husband's favorite sound because of its soothing effect. This is the reason why we fell in love with that one piece of property we visited in GA not too long ago. It has a creek with running water cascading down some rocks. Sadly we're not putting down an offer on that property for some other reasons. So if I want to hear that soothing sound of flowing water, I might as well get me one of those water fountains indoor that we can put here at home. The sound of the flowing water from the fountain will definitely simulate that of the running water in that creek at the property we like. I'm sure I can convince the husband to get one because he also likes that sound. Can I say Christmas present, maybe?
