An English teacher often wrote comments on her students' essays. She was working late one night, and as the hours passed, her handwriting deteriorated.
The next day a student came to her after class with his essay she had corrected. "I can't make out this comment you wrote on my paper."
The teacher took the paper, and after squinting at it for a minute, sheepishly replied, "It says that you need to write more legibly."
