So Roddenberry said Children don't grieve and death is accepted as a normal part of life... Ok, there's just one problem with that.
in this episode spends most of the time grieving! Worf grieves, Riker grieves, Wesley grieves, even Picard grieves a bit in front of Jeremy. Heck, near the end Picard has this to say.
Picard: Jeremy must come to terms with his grief.
It's like a life guard telling people that there's no diving in the pool, but seconds later allows everyone to dive.
