All kids need to just adjust. It is life. It is school.
Teachers come in all styles and personalities.
They are NOT all "Mary Poppins."
And being a Mary Poppins type teacher, does not make her/him better than another.
ALL throughout school, this WILL happen.
It just is.
And Teachers do NOT have to be all smiley. They are not 'Customer Service' employees. They are Teachers.
And also remember, that some Teachers may not be all super friendly, because they may have gotten "burned" by past parents, who took issue with every, little, thing, the, teacher, said, or did. HENCE.... some teachers are VERY guarded. Because even if they are "nice" and all smiley, not all parents are nice or smiley, to them.
I know. I work at my kids' school.
And, it is VERY VERY VERY VERY VERY hard, to please, all parents. Because, the parents pick apart the Teachers and make things very hard, for some Teachers to even teach, or to interact with their child as a student.
Some parents, are never happy with any personality a Teacher may have.
Being all smiley or not, does not make a Teacher better than the other.
My kids have had ALL sorts of Teachers. Some friendly some not. So what.
The Teacher, TAUGHT my kids and my kids learned, and they were happy, and friendly or not, ALL Teachers, WILL discipline any kids, that needs it. And when that happens, they are never popular.
And that, is sad.
My kids are in 2nd and 6th grade now.
And no matter what personality Teacher they had, it was FINE.
My kids, adjusted. They never complained.
