Who is speaking in "Girl"? What do we know about him/her?

The
speaker in 's very short piece is not identified. It may be inferred that this person is an
adult speaking to a child, probably an adolescent. It is possible that the speaker is an older
child, such as a big sister. Regardless, the speaker feels qualified and duty-bound to advise
the person addressed. All of this may be deduced by the use of second-person direct address
(speaking to "you"; commands). A very likely scenario is a mother speaking to a
daughter. Their excessive critical concern over potential or recent inappropriate sexual
behavior ("slut") is an indication.

An equally plausible
interpretation is that no one is speaking aloud. There seem to be several speeches run together.
The "speaker" may be alone and remembering things they once said to the
"girl." The girl herself may be remembering all her mother's or other older people's
typical lines heard throughout her youth.
