Given the up-front "return address" and the typical workings of the 13-year old mind (VS - all of civilization == "my parents making me brush my teeth and study" n'stuff..)

I'd doubt that bin-L. is juvenile - malevolent of course, but like all humorless Righteous ones *everywhere* -- incapable of even 13-year old humor. (When yer doin Gawd's Work\ufffd - terminal solemnity is.. de rigeur.)

Just my take.









(If he really Had a sense of humor, implying a functioning emotional center: he's stab himself - with a box-cutter.)
