Senior Picture Day Michele Serros As I began reading the short story of Senior Picture Day by Michele Serros‚ my expectations were low on excitement. I was expecting to read a rather bland story of how a young teenage girl had to conquer a million defeats in order to take the perfect senior picture. However‚ to my astonishment the short and sweet story pulled at my heartstrings. I could empathize with “Cal Girl” having endured a similar situation in my own teenage years. This story depicted only

6/25/2014 Philosophy 201 Reaction to Kant Kant Kant first draws close to differentiating between a moral choice and a prudent choice.

Reaction to James Joyce’s “Araby” James Joyce’s “Araby” is no different than his other works. The story of “Araby” is layered and profoundly complex yet‚ so are his other works. “Araby” is the story of a young boy who lives in Dublin and is completely captivated by a female counterpart.

Volume 1‚ Issue 1 By: Michelle Mitchell 12/04/2010 Final Reaction Paper Which would you recommend for Desktop Publishing? “I loved working with Microsoft Publisher‚ rather than Microsoft Word.

About Love The use of critical thinking is imperative when trying to persuade others. One must effectively use the three types of appeals in order to be successful. I have noticed how Danielle Crittenden and Judy Brady have used the three appeals in their essays “About Love” and “I Want a Wife.” Crittenden and Brady’s use of tone greatly effects how the audience perceives their writing. In “About Love” Crittenden’s first half of the first paragraph has a completely different tone than the rest
