I was talking to my dad about alcoholism in the construction industry (long story), and he ended up talking about an old Chinese guy who lived in the town where he grew up, which had absolutely nothing to do with the conversation. This seems to happen every time I talk to him. We'll talk about something, and he ends up talking about his work, or some guy he knew, or something he heard, or some other thing that is totally unrelated to what we were talking about originally. It's not a smooth transition either; it would be comparable to having a thread about physics and some guy posts something about Paris Hilton. One of my best friends does this too. A conversation will be about something like a TV show, and he somehow ends up talking about the different kinds of paint, and how it's made, and what the properties are. That's his job btw. He works in a paint factory. One of my mom's friends is really bad for derailing conversations, but it's very apparent that she has ADD (real ADD, not the fake ADD kids have caused by lack of parenting). My dad and friend do not have ADD or anything similar. They're both the kinds of people who will make a list of things they want on their sub sandwich, just to make sure they don't screw it up. Basically they are the exact opposite of ADD. Is there some underlying medical cause for people rambling, or are they just *******s?
