Are you one of those people that gets all new age-y and believe that what you put out into the universe comes back to you? I don't believe it so much on a grand scale, but with little things, it really happens.
When you get something that you've put a lot of thought into, like a bike, or do something you've put a lot of thought into, you start to cruise other bicycles, other people's efforts at the same thing. Bikes are so much more on your radar, then, all the details and variations and reasons, and it starts to feel like they are around you more.
So it is with opossums, say. You see one, then you start to see more, and you notice pictures of them places and mentions of them other places. Or you mention Morocco on your blog, and then start seeing lots of readers from Morocco. Or you say one little thing about balaclavas, and then you find this insane picture, by total fluke, on a religious blog that you would never visit on purpose.
That's just what happens when the new age hits.
