These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Paranoia Fuel: Playing as a human is this trope. You're afraid to talk to your friends, you can't walk to class without looking over your shoulder every few seconds, and you'll probaby end up living on ramen packets for a few days (since the average school's cafeteria tends to be a regular zombie hangout).
Tear Jerker: This happens a lot when a girlfriend or boyfriend becomes zombified. It does lead to a lot of hilarity afterwards, though, especially if they were planning on having a night together.
