You know how when you’re a teenager, you’re told you should “grow up and get a job”? Ever notice how “job” also refers to biblical texts that say at the end of your inevitable suffering, God will be with you, for he is just? Also worth noting: suffering is very close to surfing, i.e. travel via ocean, which is like a boat. Another big boat was the ark, pointing again! to the Bible. Remember when I said “grow up” earlier? That is probably because it is so close to “group”, which, with the other noted connotations, ties in with biblical stories = Bible Group. Because all of these messages come together when you are a teen, obviously we are talking about children’s Bible study. “Children’s” can be shortened to the word “chirruns”, aka “trains” so Trains Bible Study would be manufacturers instructions for freight trains, which could *also" mean “fraught trains”, because ghosts.
