My kids just roll their eyes when I get going on one my monologues about the wonders of Unix. They just barely tolerate me, like some people put up with the rants of a crazy old uncle at family gatherings.

The most feedback I've ever gotten from them was in response to one of my paeans to textmode interfaces. The oldest boy wryly observed how ironic it was that I was talking about programs running in a terminal emulator on a graphical desktop environment. I have a mind to cut off that smart aleck's inheritance!
