One possible theme could be isolation. Silence often implies being alone or cut off, and in a back story, it might show a character's struggle with feeling isolated from society or their loved ones.
Inner turmoil is also a likely theme. Silence can be a sign of internal conflict. Maybe the character in the back story is silent because they are torn between different beliefs or desires. They can't speak out because they haven't resolved this turmoil within themselves, and the silence is a manifestation of that internal struggle.
One possible theme could be secrecy. If the story involves silence, it might be about something that is being kept quiet, like a hidden truth or a confidential matter.
One possible theme is isolation. Just as radio silence cuts off communication, the characters may feel isolated from the world around them.
Spirituality could also be a theme. In Indian culture, there is a strong connection between silence and spiritual pursuits. The short story may delve into how characters' spiritual journeys are influenced by or expressed through silence.
One possible theme could be female empowerment. If she was being silenced but managed to break through, it shows the power of women to fight for their voices to be heard.
One possible theme could be resilience. Since it's based on a true story, it might show how people overcame difficult circumstances. Another could be secrecy or the consequences of hiding the truth.
There could also be a theme of self - discovery. In the midst of this long silence, the characters may be forced to look within themselves. They might have to face their own fears, desires, and secrets, which could lead to a process of self - realization and growth.
One possible theme could be redemption. A character who has made mistakes in the Twilight world might be seeking redemption and this is how they break their silence. For example, a vampire who has been living in the shadows of their past actions.
Nostalgia could be a theme. If it's a story looking back at the time when someone was in pampers, it's often about reminiscing and feeling nostalgic for that period of life. Also, growth and development could be themes. The story might show how a person has changed from being a baby in pampers to who they are now.
Another theme could be the loss of innocence. The war would have exposed people to violence and death, and those involved might have lost their naivete. For example, young soldiers going to Vietnam and coming back changed forever. Also, a theme of friendship might be present. Soldiers or civilians might form strong bonds during those difficult times to support each other.
One possible theme could be regression. It might explore the idea of going back to a more innocent or dependent state, like infancy when diapers are used.
