I sometimes keep track of synchronistic occurrences. I have a written account of some of my recent synchronicities. This is one that just happened a few hours ago.
Another blogger had reported that they had been on the ocean for a while. I commented that I'm about to go to the ocean, too. Then I went to read a page or two in a book and noticed the little globe on the cover had the word "ocean" on it. I hadn't noticed that word on there before tonight.
Synchronicity, when it happens, is something that makes me smile and take note.
