Good on you Bizzy, I think that's the best way to do it. From there you can decide what action you need to take, if any.
I personally think any parent that is labelled a trouble maker for asking questions & getting involved in their child's well being at school sucks big time...I must be a major trouble maker.
You have inspired me to attend BOT at our school, I always meant to but something always came up.
Hope it all goes well & you feel better about being there & feel welcome.
Remember, head high, back straight & hold DH's hand under the table if needed
