I've done a lot of stupid shit as a professional. One time I had a hearing in county court. I was representing the plaintiff in a simple collections case and the defendant had never shown up for anything, never filed an answer, never responded to my letters or phone calls. So we're at the hearing, and I ask the judge if we could take up some other matter in the case. The judge asked if I had noticed the issue for a hearing and I said no, but the defendant never shows for anything so I thought we could just go ahead. She asked me, "Don't you think that would violate Rule 21 of the Texas Rules of Civil Procedure?" I didn't know what the fuck Rule 21 was so I had to say, "I don't know." The judge just looked at me incredulously and asked if there was anything else. Rule 21 is one of the most rudimentary rules of civil procedure that says everything you file in court has to be noticed to the other side. Basic due process. I felt like a real idiot that day.
