"You have to sign this petition! It's to get Congress to require all envelopes to be self-adhesive. When you lick an envelope flap, the Post Office runs it through a scanner that takes a DNA sample. Then they match that up with your name based on the return address. Homeland Security claims to be keeping the information to know how best to protect Americans from a gene-based terrorist attack, but if the wrong people came into power, they could use it for eugenics and put everyone with a certain chromosome combination into concentration camps! So will you sign the petition?"

tinfoil hat 

Propoganda designed to cover up a massive government conspiracy. Begining in the late 1970's, the United States government tried to cover up its radio-wave thought-control program by circulating a false rumor that people could shield their minds from government intrusion by wearing a tinfoil hat. In truth, a tinfoil hat only improves reception and makes it easier for the government to read your mind. Speak truth to power!

Sister: This meeting was to discuss the rough draft of my essay, where we discussed the subsidiary questions I added in my rough draft. We also discussed the relationship between my main title and the real-life situations I chose to use in my essay. We discussed the structure of my essay as well, specifically the Math AOK section and how it relates to the contradiction of the title. This second meeting was particularly helpful in discussing the implications of my essay claims and how to apply the title across various areas of knowledge. There were many sections of the essay that could have been cut down in wordiness and the ways of knowing required further and more in-depth analysis.
