In fairness, it is entirely possible that the parent was correctly indicating the location of a salient / appreciated point in this discussion thread ;)

I'm not OP, but that's unlikely. This is general language construct and is used in the beginning. No one use "here here!" :D

Just use ockham's razor, would you suppose he misspelt a general language construct or created a whole new one? :)

I can end this post here, but I want to mention one more thing I'm reminded of: In Sherlock Holmes TV Series (don't remember the episode), a woman dies while writing "Rache" in her own blood. Other characters tell him that Rache is revenge in German. Sherlock posits that she was trying to write "Rachel", a much simpler (I mean with less assumptions) assumption to make in the context.

"HN Pedantry" is rubbing off on me :D

The funny thing about "Rache" is in the original story it was the other way round. :)
