After seeing the pile of papers returned for reworking a third time, I was set to leave school. I appreciate you sparing my emotions. I'm not sure what you did, but it appears to be the proper combination to the lecturer's heart. Get prepared for more interaction from me! How did you manage to achieve this? I was on the verge of giving up trying to locate anything on that trivial matter for weeks. But thanks so much for the wonderful materials you gave me!
