annoying teachers!!!!

teachers just absolutly annoy me!!. so i am taking rather easy classes because i have the majority of my classes done. my only two "hard" classes i am taking is algebra II and english IV. anywho, i take a computer apps class with a class entirly filled with freshmen! no joke. so the teacher assigned a task yesterday for the class period and i completed the task in 10 minutes. therefore, i took out my algebra and began working on it. well no no no. im not "suppose" to do that apparently. the teacher came over and asked what i was doing. i said working on algebra because i finished my task for the day. so she asked to see it. i showed her. then she said good job now find something else to do. so i said im working on my algebra!. like hello lady, how many times i got to tell ya!. lol. so she said i need to work on something pertaining to this class. but she did not have anything for me when i asked for her to give me something. i said what is the difference in me working on this algebra vs the guys across the room surfing the internet. i mean i was done. they probably have not even started. wheew she pushed me buttons way over the edge!
