When opinions don't matter.

Disappointed, not with the fact that you decided to go ahead with something you felt justified; but for the fact that you did not highlight your actual intention at all.

There is a problem that people want to communicate and have lost sight of the difference between a conversation and communication. However, it seems the discussion of ideas and opinions isn't really a case of one or the other. It tends to be someone who doesn't agree with you wishing to point out the error of your thoughts.

Well, I guess it's really like what you said - my opinion is not required.
