Nervously I look out. I can't see any tripods! Where are they?

I step outside. The red Martian weed seems to be growing everywhere.

The Earth must be looking more and more like Mars. This is no longer our planet. Then a local dog notices me and runs up, barking at the door where I'm hiding. the Martians will hear him!

Should I use the meat cleaver and silence him? Or should I accept that I can't hide for the rest of my life, and step outside? Or do something else?
