Learn, Lo, Learn.
Co had to calm me through it, though I mostly picked it out myself. (Please note Co's other blog, in case this surprises you even remotely.)
On the other hand, it was my passionate desire to create the fancy new (okay, anal retentive new) categorization system that brought me to the point where I actually asked of my own volition what "ul" means.
One of these days I might even be able to communicate with 12-year-olds. (However, I will never set up a myspace. Never. Never. Never. Never. Though I must add that, if any of you have been following the myspace drama in the news, the word on the street from my local 12-year-old users is that it is "so over." Okay. Works for me.)
