One possible theme is self - acceptance. Discovering one's homosexuality and learning to be okay with it. Another could be the theme of love, the first time falling in love with someone of the same gender. Also, the theme of courage might be present, as it often takes courage to face the world when realizing and accepting one's gay identity.
Inclusivity could be a theme. The first gay hike story might show how the gay community creates spaces for themselves in an activity like hiking that has traditionally been dominated by the mainstream. It could also be about the joy of nature. Gay hikers experiencing the beauty and peace of the natural world, away from the judgment and discrimination sometimes faced in society.
Acceptance is a big theme. It could be about the struggle to accept oneself as gay, especially when faced with external factors like family and society not being accepting. For instance, the character might be worried about being shunned by their family or friends. Another theme could be the journey of breaking free from internalized homophobia. They might have grown up believing that being gay is wrong due to the environment they were in, and they have to overcome this self - imposed barrier.
One possible theme could be self - discovery. Discovering one's sexual orientation and coming to terms with it is a big part of such a story.
One possible theme could be friendship. Animations often revolve around characters forming bonds and helping each other out.
Nature and its beauty could be a major theme. Geese are part of nature, and the story could be about the wonder and awe of experiencing a goose in its natural habitat for the first time. It could also touch on themes of growth, as in the growth of understanding about the natural world through this encounter with the goose. Also, the story might carry a theme of simplicity, highlighting how a simple encounter with a goose can have a profound impact on a person.
Another theme could be about the complex relationships among multiple individuals in a sexual context. It may depict how different personalities interact and form unique dynamics during such an encounter.
Another theme might be discovery. The story could be about the discovery of the goose as an interesting and unique part of the world around the narrator. It could include details about how the narrator learns about the goose's habits and characteristics, thus representing a broader theme of discovery of nature. Also, it could touch on the theme of fear and courage. If the goose is intimidating at first, the narrator's journey from being afraid to perhaps befriending it could show the development of courage.
One common emotion could be confusion. Since it might be the first time experiencing such feelings towards someone of the same sex, it's natural to be unsure about what it all means.
The theme of infatuation could be present. The story could be about being head - over - heels for someone and that first French kiss being the culmination of those intense feelings. It shows how strong emotions can lead to a very physical and memorable moment.
One possible theme could be loss. Since it's about a first lover who is now like a shadow, it might be about the loss of that relationship and the feelings associated with it.
