It could be about their first time participating in a community event as amateurs. They may be nervous at first, but as the event progresses, they start to contribute in their own ways. The story might focus on their self - discovery, how they realize their potential and how this first - time experience changes their perspective towards the community and themselves.
It could be about two siblings who are amateurs in a particular activity and are experiencing it for the first time. For example, they might be trying painting for the first time and the story could revolve around their initial clumsy attempts, the mess they make, and how they gradually get better. Or it could be their first time camping, facing challenges like setting up a tent and starting a fire.
