Flush with a newly successful business venture and the joy of being reunited with old friends, I became overly rambunctious at a convention several years ago. I still cringe at the memory of babbling incessantly as a talented folk-rock artist glared at me from a nearby stage. I know, consequently, that jerks are often merely oblivious rather than malicious. Even so, I have low tolerance for similar rudeness in others. Please- just stop talking.
