While we're talking about cereal, I'd really like to voice that I enjoy special K cereal, but the "Special K diet" is baisically "eat chocolate protein to loose weight". I tried it for one week and I felt like all I was eating was chocolate for breakfast, lunch, and snacks. Don't get me wrong, I love chocolate, but it's probably not the healthiest way to lose weight (off-off-topic, that's the only diet I've ever tried. I tend to just try to be a "healthy eater" most of the time).
^Oh, you mean like that?
I guess it's just because one idea leads to another, and it's hard to prioritize what information to give to the person receiving your message (spoken, typed, gestured, etc). The vicious circle I fall into is that I say something, then need to clarify it, then add information to the clarification, then need to clarify the added information, etc. At some point my conversational partner jumps in and interjects something about the new information or the clarification, then of course, I feel the need to respond to his/her comment. Then I clarify, etc., and a conversation about physics homework becomes a conversation about the possibilities of ballet dancing on the moon.
