Answer:
I’m kicking myself for eating that overripe fruit - reflexive pronoun
He himself asked me to send him an invitation - intensive pronoun
She busied herself with signing the documents - reflexive pronoun
I myself was surprised to see him back so early - intensive pronoun
Explanation:
While intensive and reflexive pronouns both include myself, yourself, himself, herself, itself, ourselves, yourselves, themselves, these two types of pronouns are used in different situations.
<em>Intensive pronouns</em> are pronouns which add emphasis to a certain statement. As in second sentence given above - "He himself asked me...." We already have the subject of the sentence, but the pronoun 'himself' places emphasis on it.<em> Reflexive pronouns</em> are used when the object and the subject of the sentence are the same. For instance, '"She busied herself with signing the documents."
