Identify each sentence as containing a reflexive pronoun or an intensive pronoun.
I’m kicking myself for eating that
overripe fruit.
He himself asked me to send him
an invitation.
She busied herself with signing
the documents.

back so early.

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.

Intensive pronouns 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. Reflexive pronouns are used when the object and the subject of the sentence are the same. For instance, '"She busied herself with signing the documents."
