[TheForge] relearning ... or ... I knew that

[Phlip]

S'OK, we all suffer from mind farts occasionally. My roomate fires up the
coffee pot at least once a week, and installs water, changes the filter, and
forgets to add the coffee. I've taken to loading it before I get to bed,
because I'll load it in the morning, and forget to turn it on. Pushing a
button, I can handle, as long as there are no other complications....
