Here's why:
* Pronouns are generally considered "minor" words in titles.
* Capitalization in titles follows a specific set of rules:
* The first word is always capitalized.
* Major words are capitalized (nouns, verbs, adjectives, adverbs).
* Minor words are not capitalized (articles, prepositions, conjunctions) unless they are the first word of the title.
Examples:
* Correct: "He's a Pirate"
* Incorrect: "He's A Pirate"
* Correct: "What She Said"
* Incorrect: "What She Said"
Exceptions:
There are some exceptions to this rule, mainly when the pronoun is part of a proper noun or is used as a title. For example:
* Correct: "The Adventures of Huckleberry Finn"
* Correct: "She's Got It Bad" (a song title)
However, it's important to note that these exceptions are relatively rare. In most cases, pronouns are not capitalized in titles.
