Inspired by a range of commentary from colleagues and peers, it strikes me that a number seem to comment about bad experiences in primary, secondary, or both. Thankfully nothing major, but bad memories nonetheless.
There are not going to be absolutes here, or nobody could be positive, but thinking about school memories on the whole. I remember a mixed bag, but broadly positive especially in secondary school, wondered if that is unusual.
YABU - generally speaking, school was awful for me
YANBU - school was OK, mostly happy memories
