Parents Evening is that joyous, annual event who everyone dreads, albeit for different reasons.
In lower school, this usually requires you to pre-book three minute long appointments with your teachers via insight, which are completely and utterly pointless, as you will always be stuck behind a parent who insists on having a 30 minute discussion about why their child should have a B+ and not just a B, and before you know it the whole evening has descended into chaos and delay with the bell ringing every 3 minutes to try and rush teachers and parents along.
It is very rare you will actually finish a chat with a teacher in less than 3 minutes so it is unsure why it is organised this way.
Some teachers get fully booked very quickly, these are often the nice ones that students hope will spout some story about being conscientious and a quiet yet thoughtful student to their parents. Other teachers often has less visitors as they have a tendency to be (somewhat brutally) honest, one example from the bright and cheerful Miss Wilkes includes: Miss Wilkes looks from parent to parent, before whispering loudly with a look of terror “Your son…" (leans in) "…is horrid.”
