I find it odd that there is so much teacher bashing on here based on what a parent said her child said about what the teacher said.
Perhaps the teacher was trying to be funny, perhaps the child misunderstood, perhaps...a hundred different things. I can completely seeing the teacher making a joke about walking--trying to be funny. Sometimes kids don't pick up on sarcasm or humor.
To say things like this: and and calling him a bully, based on the original post strikes me as really unfair.
My five and seven year old have come home with all sorts of things they claim happened at school. As a teacher, I've also heard some doozies. If I was really concerned, I would contact the teacher to get clarification. As teachers often say, "Don't believe everything you hear from your kids that they say happened at school, and I won't believe everything they say happens at home."
If people really think that this teacher is not fit to teach children based on a casual comment in class (about walking to Disneyworld of all things), then I think that's really sad that there is so little trust in our teachers.
