look at the old recording tape and the old fasioned phone...this suggests that the game was set in the seventys or something like that meaning that you were allowd to hit children with rulers if they were naughty.when the princible says to himslef "when will you learn" it means you have been in detention a few times.also look at the school rules you break the school rules so thats why baldi wants to smack you with a ruler.You may think that question that no one knows is realy hard and baldi did it on purpose but its actually just because he blelievs in you and wants to challenge you.When you get a question write baldi complaments you saying something like "great job" or "heh heh you got it!"Thats what a good teacher should do.
