Never! Unless: I get PIA(PERMAD IN ACTION), hack pwned, killed, or if SDK gets sewed by nintendo and then gets shut down, or when the interwebs explode, or any other extreme case scenerio. iow: never.
two books you must cover are The Hobbit by JRR Tolkein and Soldier Boys by uh... i forgot. Theyre bolf great books but the 2nd i dont think 3 year olds should be reading because of the ww2 gore n stuff described in the book. the book has some gore and stuff that may not be suitable for 5 year olds so yea.
