Re: A note from your child's teacher...
I'm sorry OP that you feel frustrated. It's certainly an individual thing. If those are the boundaries you want to set then I'd be very clear with parents from day 1. Hope it works out.
Personally, it's just par for the course, and I'm 'just a para' right now I get stopped in Walmart a lot, I've had calls. My son's teacher gives her number to all parents and says to call/text any time. He's in the ASD unit granted and often times parents just need support with the special needs aspect so she makes herself available.
Sometimes the grass is greener on the other side!
