Lost money coincidence.

I was living in St. Leonards-on sea, about twenty years ago when my strange event happened. There was a small co-op store nearby, which i would shop at regularly. I lost a five pound note in an isle, which was very unlike me. I remembered exactly where i dropped it, and two days later i found a five pound note in the very same place. "That's a coincidence" i thought to myself. I must say, while i'm here, that my husband often comments on something being weird, and seems to happen particularly to me. I reply that thousands of small events happen every day, which nothing is noticed or commented on. I think if everything was recorded, it would not seem quite as odd. I would absolutely love to know whether i am on the right track or not. Thanks, Lucy Pine
