Have you ever looked at something and swear that it's not what you saw? For example, you see a bright light in the night sky it moves side to side; it starts to get bigger then smaller. It goes up and down then it goes down again, you're sure it's a ufo, but suddenly it gets loud. The louder it gets the more you are convinced that it's only a helicopter, wow! no invasion on earth tonight! Things do not always appear to be what you expect so when my professor gave us an en exam today everyone was up in arms. It read the following: "Read everything before you do anything, 2-write your name in the upper top left-hand corner on this page." Between numbers 3 to 19 was jebberish. It was number 20 that blew my mind and everyone else'.  It read: Now that you have finished reading the directions carefully, do only sentences one and two. Sit quietly until everyone else is finished. Some students didn't understand what was needed by them some even got annoyed because they could not understand, it was so simple once realization stepped in. How silly, sometimes we take perception out of context today our professor taught us a big lesson "things aren't always what they seem."
