Not a Boomer, but I don’t understand how following a conversational thread is “Boomer.” Don’t you understand how conversations work? When you are with your friends, do you generally declare a topic, then scold them if they wander off topic?

Because that’s not how friendly conversations work. You never really know where they’ll lead, and that’s what’s enjoyable about them. The guy sitting at the table and telling people to stay on topic is a real buzzkill, and right now, that’s YOU.
