What if you had to briefly summarize the questions: What is a Mason? and What is Masonry? If you had to, could you explain this to the profane -- without boring them with detail, yet with enough information to be meaningful?
Here's my stab at this. Feel free to share yours as well.
------------------------------------------------------------
What is a Mason?
A Mason is a good man who wants to be a better man. He has bound himself to other masons by promising to follow certain rules, most importantly the Golden Rule, especially when it comes to fellow Masons. A Mason may have any economic status, faith or color.
What is Masonry?
First and foremost, Masonry exists for the spiritual improvement of its members. Masonry uses rituals, allegories and symbols to convey morality to its members. Masonic teachings include the tenets of Brotherly Love, Relief and Truth, and the cardinal virtues of Temperance, Fortitude, Prudence and Justice. Masons believe in equality, democracy and patriotism. Once conveyed, it is up to each Mason to incorporate these teachings into his own life.
Masonry channels a Mason’s desire to give to his community through formal charities, like Shriner’s Hospitals (treating children, http://www.shrinershq.org/ ), 32 Degree Masonic Learning Centers (treating dyslexia http://www.childrenslearningcenters.org/home.html ), and programs like MICHIP (Michigan Child Identification Program http://www.michip.org/).
Masonry also serves as a social outlet for members of the fraternity and their families.
