Wiktionary example

These source excerpts show how pessimism appears in context. They illustrate usage; the definition above remains the entry’s reference meaning.

  1. T2 isn’t as good as T1: it is a little too long and unwinds a bit into caper sentimentality, broad comedy and self-mythologising.
