I understand a genre as a particular style of writing with specific purpose and audience.
Science Fiction, Children’s books (Picture books), Journaling, Email, Texting, Comics, Novel, Letter, Commercial Slogan, Research paper.
My favorites are the first two:
Science Fiction compelling to me because it present imaginary reality which rooted in scientific fact and it makes it convincing and remotely possible.
I love Children’s books (Picture books) because pictures are often tell more then words and simple words conceal big ideas.
