Who do you think the speaker is? Why? (grammar / point of view) Indian Boy Love Song (#2)

I never spoke
the language
of the old woman

visiting my mother
in winters so cold
they could freeze
the tongue whole.

I never held my head
to their thin chests
believing in the heart.

Indian women, forgive me.
I grew up distant
and always afraid.

I think the speaker is an Indian boy who doesn't feel accepted because he isn't able to speak his mother's language. He's afraid because he doesn't feel accepted.

Digraphs are indeed combinations of letters, however, they are combinations of only two letters (di- means two in Greek). Additionally, these combinations don't have to be only consonants, but rather vowels as well. Combinations of two or three consonants are called blends, not digraphs.
