Come Home Beautiful

There was a whole series of these letters posted along Swan Street, Melbourne about a month ago, all handwritten. Most of them were torn down before I could get a photo, but I managed to get one.
Text reads:
COME HOME BEAUTIFUL
WE ARE MAKING SAFE
HAPPY AND WARM US ONLY
(WHICH MEANS YOU TOO) HOUSE, AND
IT WILL STAY THAT WAY
NO SCARY INTRUDERS
PLEASE PENNY MUMMY LOVES YOU
I DON'T KNOW HOW TO LIVE WITHOUT YOU.

Swan Street, Melbourne.
