Finally, it happened. I didn't meet the deadline for the post on April 15th. I was procrastinating right up to the limit, took a while to find a topic, went overboard trying to add things to it, things happened, and I didn't make it. "Oh, so you surely took advantage of the 15 days until today to work on it fully, right?"... Well, no, my dear, I'm finishing it up on the day it's supposed to be published, as always. I never learn.
