The thing that happen on May 2012 9

In the Language Arts class (L.A) when Ms.Penny let the 4A class write the short sentence (The sentence that we write it short for example: We are studying for the quiz=We're studying for the quiz) and when it's Rei's and Harshitha's turn to write, Ms.Penny accidently give them the permanent marker, and they both don't know it's that kind of marker. When Harshitha spell the word 'Lady' wrong, I help her to erase it, but it cannot erase. Then I figure it out it's a PERMANENT MARKER!!!!! Ms.Penny thought that we were just joking, but once she got the smell of it, she is in a panic, and the whole class 4A gather the board and try to solve the problem how to erase it.
