I think you and most other people in this thread are making an unfounded leap about what was written in that report card, based on the politics of OOP. But OOP says it was a report card - which is a normal, regular thing to send home with a child. There is no indication the child was sent home early, or that what was written was any kind of repremand. No where does it say that OOP's child made anyone cry.

Presumably, this is an expensive preschool for the children of silicon valley elites, who want their children to recieve an education that will prepare them to be extremely high earners and leaders in industry. These sorts of people typically do acknowledge the large component that being socially aware plays in one's success, and the preschool is likely offering updates and help on social/emotional development as part of their service, since it is something that the parents want. If OOP's child was making other children cry, this info would probably be brought to the parents immediately, since regardless of how wealthy and high status they are, all the other parents are also wealthy and high status and would raise a stink about their kids getting bullied. Otoh, "your kid avoids eye contact and never plays with other kids, just does math and plays with legos alone" would be a fairly normal thing to discuss in the social-emotional development section of a report card.

Similarly, I never said lemmings arent nice. But I would bet that if you gathered a bunch of them together, they would stand around nervously for 45 minutes and just listen to 3 people talk who happened to stumble upon a shared special interest.
