We are like islands in the way you wrote of...individuals trapped in our own little worlds, yet floating around independently, but covered in a sort of membrane (much like a blood cell) which is permeable. We receive information and energy, as well as give information and energy. But rather than being an island, I more think of us like rubber ducks in a big tub...surrounded by water, bumping into each other on occasion :) We ARE all in this thing together, but also, at times, very much alone. (Perhaps the blood cell idea is actually better than rubber ducks, but the ducks are cuter!)
I wish, often, when I'm alone and thinking of someone one far away (blog friends, dead loved ones, or people who live in Alaska :) that there was a way to break through the barrier of time, space, and location and simply communicate. Sometimes I do speak, almost prayer like, to the person I'm thinking of. The alternative, of course, is texting- which is almost as good, except it doesn't seem to work with the dearly departed or bloggers in other countries. I guess this is why we have computers and email? ;)
Above all- what I read and feel in this post is about connection, as well as lack thereof. It's the thing that tickles my brain too...wondering how and where I fit in, especially now that my "place" in the world is radically changing as I watch my kids go and emerge into adulthood. My baby rubber ducks aren't paddling behind me anymore...
The best question I should be asking is, "WHAT do I want to do now? and How?"
