Even an angry teacher will state a question (a rising inflection on
the last word/syllable of a sentence).

Punctuation reflects these changes in inflection/speech patterns (like
periods signaling long breaks, as are common to end a sentence, comma
signaling shorter pauses within a sentence which usually imply
additional information about the preceding topic, and so on).

TL;DR: Parsing a natural language is *hard*.

Though the folk I have met,
(Ah, how soon!) they forget
When I've moved on to some other place,
There may be one or two,
When I've played and passed through,
Who'll remember my song or my face.
