For the Record:
#2. On the flip side....if you are obese...(I'm talking about people who have several rolls between their knee and the place where their ankle is supposed to be)....please do not make statements about your fatness as it makes unfat people feel uncomfortable and awkward. You needn't state the obvious because most people can not miss you or your size. Nonfat people already have guilt eating delicious burgers in front of you. And please hold eating super-sized value meals in public....its just disgusting for all surrounding parties involved.
And if you do not know where you fall...then assume you are skinny and don't say anything at all....as hearing about personal weight dissatisfaction is both annoying and a waste of time. If you are fat, then eat less and you will lose weight. If you are skinny, then just shut up.
