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.
Mary Sue: In the alt text of this comic, John reveals that he had taken the Mary Sue litmus test and in-comic John had scored squarely in Sue territory. Ouch.
Moral Event Horizon: Subtle because the comic is Slice of Life and the characters aren't going to go off murdering one another, but within the moral framework of the comic, Elly, John and Harry have crossed it.
Obligatory Swearing: May be justified since the characters are all in their early-20s and the dialogue is supposed to be realistic. The author said in his Alt Text that he believes The Word Weary is the comic with the most uses of the work "fuck."
This Loser Is You: Possibly played straight in that John's doubts and insecurities are played for laughs and relatability, possibly justified in that the character is heavily based on the author and not meant to represent the comic's potential audience.
