There are likely to be his colleagues at work. They contribute to the corporate environment that he is a part of. They might be rivals in some ways or comrades in others, all of which shape his experiences at work. Also, his boss could be an important character as he is the one setting the rules and expectations in the corporate hierarchy.
The theme of identity is prominent. The protagonist is constantly grappling with who he really is within the context of his work, family, and society. There's also a theme related to post - war America. It shows how the post - war economic boom affected individuals, pushing them into a rat race where they had to sacrifice personal aspects of their lives to fit into the new corporate and consumerist culture.
The cultural context can be a factor too. A cologne with ingredients that are native to a particular region might tell a story of that place. For instance, a cologne with oud from the Middle East could tell a story of the rich, exotic culture there. The scent can transport you to that place and give you a sense of its traditions, people, and history.
Well, it could be that Harry is raised in a world where cologne has some sort of magical property. Maybe the scent of a particular cologne is used to protect him or give him special powers. For example, the cologne might be made from rare magical ingredients and whenever Harry wears it, he can blend into the Muggle world more easily because it masks his wizardly aura.
One benefit is that flannel stories are often very visual. The use of flannel boards with movable pieces can capture a child's attention easily. For example, when telling a story about animals, the flannel pieces representing different animals can be moved around, making the story more engaging.
Another character could be a cologne - making elf. In the wizarding world, there could be elves who specialize in making colognes. This elf could have a special bond with Harry. It could be that the elf was tasked with making a special cologne for Harry's protection from the moment he was born. And as Harry grows, the elf helps him understand the true power of the colognes he has been surrounded with all his life.
Well, for a family flannel board story, think about the values or emotions you want to convey. Is it about family love? Or the importance of family unity? Once you've decided on that, you can start creating the story. For instance, if it's about family love, you could tell a story of a child getting sick and the whole family taking care of him. Draw pictures of the sick child in bed, the parents bringing medicine, and the siblings reading stories to him. Put these pictures on the flannel board while telling the story in a warm and engaging tone.
I'm sorry, I don't know the specific 'little mouse flannel story'. Maybe it's about a little mouse's adventure in a world full of flannel things, like finding a warm flannel nest or making friends with other flannel - loving creatures.
