To be that parent?

No, I am only semi serious. I've no intention of giving DCs teachers a hard time.

However, I do remember the days when I was at school, where you got into trouble and an adults word was law, and getting into trouble at home as well.

AIBU to not blindly accept the teacher's version of events when it comes to my DCs?

Well, I always want to hear DC's version of events. Quite often I've found that it's more like 90% the teachers version, but 10% of DC's version.
