Mr. Wiggly's teacher sounds a lot like C-dog's teacher last year.  I actually dropped in and peered in the window unannounced to see what was going on.  I saw a circle time story with C-dog sitting way in the back, far from the group with a look of pure pain and sadness.  Practically a quivering lip.  After school I asked the teacher in an upbeat way:  "So how was C-dog today, she seems a little sad?"
"OH NO!, Not at all!"  "She had a wonderful day and was very happy?".
She's either severely clueless or simply evil.
She is mean.
