I understand your point.
I simply don't care about other people's assumptions. People see and understand what they want.. Regardless of how well spoken. If people are interested they ask. Otherwise they can assume what they want..
Its always been a good litmus test for my interest in them as friends or otherwise.
Besides it can be fun to leave communication room to breath. Makes for some interesting discussion with the right group of people.
My label laziness could simply be a consequence of my job. I can't allow for assumptions in my work place. I build documentation and policies for it infrastructure and the training to go along with it. I don't carry that skill's into my personal life.
