It happens all the time but usually we don't think anything about it. You may think about someone and they call you or you make a wishful statement and the perfect situation occurs right before your eyes. Do you call it a coincident or is that experience letting you know that there is someone out there in the Universe that has got your ear and is paying attention to your wants and/or needs. When things happen for a reason, that is when serendipity comes into play. We say, that was meant to happen; it is part of our destiny.
