Watch Shaun of the Dead for some good tips as Willbur said two years ago.

Bigred also nails it without being too specific - food, water, shelter. Gotta board up the windows, lock the doors, keep the noise to a minimum and above all (this is important), if one of the children you teach gets bitten, the other kids must kill him/her as quickly and brutally as possible.

When you write that last bit on the board, underline it twice.
