This isn’t a stealth brag. Both of my DCs can be a right PITA, and I know that they both have their strengths and weaknesses.
Their primary school reports always make them out to be perfect angels, who are borderline geniuses, and I am fairly sure this isn’t the case. Aibu to expect reports to have some resemblance to reality? Otherwise what is the point? I have asked around parents from other primary schools, and it seems it’s standard nowadays.
