SoulRiser has grown enough to realize that the School Survival Forums were never really all that useful, but has not yet grown enough to realize that it was because of the reality of human (teenage) nature, not because of their own limitations. And they have been stewing in this revelation for 16 years.
There's a lot to unpack there, and I guess at the end of it I just feel that the closure of the SSF was for the best.
