As Phin and others have said, the long lasting damage isjust starting to manifest itself. One thing that is really showing is how some parents are really not able (for whatever reason, in many cases not their fault) to help their kids... they were 100% dependent on the physical school building and the staff being there for their child.
The resiliancy of many kids is astounding though. As we get more and more back, more and more kids will be getting better. It won't fix all ills, but it is something.
Not sure how we will fit them all into the cafeteria though...
