Red Ink

My professor discussed with me my written report.  It was filled with red marks.  I looked at his pen and it was an expensive one.  I worried that he might use up all his ink.  After explaining to me everything, I couldn’t help but tell him, “Sir, I hope you didn’t use up all the ink of your pen writing and checking all of these :)”

He laughed…and agreed.  Next time, maybe it’s better to use pencil in checking my paper.  🙂
