Dr Sim believes in reformation from within.
1) He doesn't know the meaning of the word "Reformation."
2) He doesn't know that you can't fill old wineskins with new wine.
3) He has been in Australia too long.
4) He is using his heart too much at the expense of his head.
5) He has not spoken to George Chan.
6) He is gullible enough to believe George Chan.
7) He thinks a BBQ can bring about reformation (from within mah).
This is said tongue-in-cheek. Unless he changes lanes without signalling.
