So many lessons to choose from here…
Don’t explore alien ships. Period.
Never take your cat into space.
Don’t cheap out on lighting when building spacecraft.
Always follow quarantine procedures.
Good advice for dealing with zombies too with a few adaptations.
Don’t explore spooky buildings. Period.
Think very carefully about attempts to rescue the cat.
Don’t cheap out on lighting. Blinky lights, spot lights, whatever. They are all good.
Always follow quarantine procedures.
Note that quarantine as a zombie-management strategy has many drawbacks. I’d have to say firearms and brain scrambling are clearly the better choice for stranger-danger zombies. Family-member zombies can be locked away. Just make sure you have sturdy doors and quality locks. Nail some 2 x 4s in front of the doorway as a finishing precaution.
If I have to tell you to pick a room without windows, well, maybe like Kim and Kanye you should just go hug one of the undead and get it over with.
