Ah, social anxiety. Yep. My first recognition into info dumping and realizing people didn't care was in my late 20s. I really find copyright law and technology fascinating. I loved tech dirt blog at the time. I started noticing that people's eyes would glaze over and the conversation would die. (I'm sure I did this before but never noticed.)

Nowaday, I drop a nugget or fact and let them ask me if they want to know more. It's a skill.
