A "Hoarse" of a Different Color

Last week I experienced something different with my class.  For two days, I lost my voice.  Despite the fact that I was too hoarse to talk, I went to school anyway.  I didn't know how my class would behave.  I assumed that they would be bouncing off the walls.  Well, you know what they say about those who assume.  I went into class and much to my surprise, they behaved better than they ever have.  I guess they felt pity for my lost voice.  That was one side of them that I have never seen.  And that was definitely a "hoarse" of a different color!
