(in case you can't tell what this is, it's a self-portrait of an astronaut, taking his own picture while looking down at the earth. The earth--and the camera--are reflected in his spacesuit helmet)
One of the most interesting things about being a parent, or a teacher (or, really, just a moderately aware and sensitive human), is bumping up against the fact, from time to time, that your perception and understanding of reality may be radically different from someone else's. My elder son was born in 2000. He has never known a world without cell phones, email, the Internet, DVDs, TiVo, and so forth. And okay, yes, that's just a bunch of gadgets. But the way they affect and inform his dealings with the world around him, especially as a given, a from-birth assumption, make him somehow different from me--maybe a little bit; maybe a lot. And if I talk to him from inside my own assumptions, without taking his into account...do I know that we're actually communicating? I know what I'm saying, but do I know for sure what he's hearing?
