Master has just told the parable of the 'injured man' on the road... when a traveler stops to assist, the body jumps up and turns out ot be a robber...
Master : ....and what have you learned from this my sons?
Fighty angry kid : Trust no one Master (in snotty snarly voice)
Grasshopper : All is not what it seems (soft enlightened voice filled with wonder)
Expat : If some one appears to be lying in the road injured ....drive over them (in strident Oz/Brit/Jermin acent)
