The theme of growing up and maturing could also be present. Hating to wait is a childish trait, and as the story progresses, the child may grow and become more mature by learning to wait, which is an important part of becoming an adult.
One possible theme could be patience. Since the title says 'I hate to wait', it's likely that the story is about a child learning to be patient.
Another theme might be self - control. When a kid hates to wait, it shows a lack of self - control. So the story could be about the kid developing self - control through various experiences in the story.
I'm sorry, I haven't actually read this specific 'I hate to wait kids story'. But generally, it might be about a kid who is impatient and doesn't like to wait for things like waiting for the bus, waiting for their turn in a game, or waiting for dinner. Maybe through different situations, the kid learns about the importance of patience.
One possible theme could be competition. Kangaroos compete for resources, mates etc., which can lead to both love and hate situations. For example, two male kangaroos might fight over a female, showing hate towards each other in that moment, but also there's the underlying drive of love for the female.
Another theme could be growth. For instance, the two kids might start out as immature or inexperienced but through the events in the story, they grow and become more confident and capable. Maybe they learn to face their fears or develop new skills.
One possible theme could be animals. For example, the quilt might have pictures of cute animals like bunnies, kittens, and puppies, and the story could be about their adventures in a magical forest.
Friendship is likely a theme. When dealing with the mystery of the seven chairs, the kids would probably need to work together, which would strengthen their friendship.
One possible theme could be friendship. Tom Aegura might make new friends during his adventures and they support each other through difficult times.
One possible theme could be self - discovery. Emma might find out more about her singing abilities and her own identity through the Voice Kids experience.
The theme of redemption could also be present. If one of the characters has done something wrong in the past that led to the 'hate' from the other, the story could be about that character's journey to redeem themselves and win back the love. It's all speculation without actually reading the fanfic, but these are common themes in stories with a 'hate - love' relationship.
Friendship could also be a theme. In many of Karan Johar's works, relationships are central. If white kids are in the story, it could be about the friendships they form with other characters, perhaps bridging cultural gaps and learning to understand and accept each other. This would be in line with Karan Johar's style of highlighting human relationships and emotions in his stories.
Perhaps friendship could be a theme. Since there are seven kids, they might rely on each other and form strong bonds.
