First, am not ca girl in Tex no more, have no idea why i used this other than back when i was in school Texas. No argument with Texas, CA home, and almost totally there, want to get to coast, if it is still there.
Anyway, it is just a silly example of what you write in the public domain can and may embarass you, your sisters.
Want to have a temper tamtrum or even if you feel you really have been wronged, just write it out for yourself first, even if it is page after page. Then, put it away overnight, read it the next day, and you might find yourself asking "Who is this person?"
Having an argument with a room mate, sister, chapter, your school, whatever, try to find someone to listen.
Many prospective employers are turning to Facebook and the like to learn more about job applicants--do you really want drunken dancing on top of tables or a rant to represent who you are?
Having worked in the media, reporters looking into matters are aware of online sites too. Nothing like a credibility problem for you, your house if things are public, and yes, that includes Facebook. Ditto all those cell phones with cameras. Zip, into the computer, and yes, the whole world can watch.
