I find it really rude when people are obviously just waiting their turn to say their prepared statement. It means they're not really listening to the other person, thus it's not really a conversation. Should someone keep score when that happens?
So when those people are supposed to express their position? Prepared statement is another way to say that some thinking was put into it vs. just blurting out the first thing that comes into mind. So, the former is rude while the latter is respectful?
A prepared statement may or may not be well thought out, but even if it is, ignoring the current context and not directly addressing the other party's arguments or concerns means you're hijacking the thread of conversation and implicitly dismissing the other party's statements.
if you wanna the other participants to drop everything in their heads, drop their arguments and concerns and start addressing yours you better put some work into it to make the arguments and concerns relevant and engaging. Not doing it or failing to do it and crying out "rude! highjacking!" instead is kind of rude and disrespectful to the other participants i think.
I wonder whether/when we would see meeting software including "karma" feature so people could just "-1" and move forward without wasting time/effort, though "-1"ing say your manager, even if anonymously ... :)
