Here is a draft profile of my best friend using noun phrases and pronouns:
My best friend Sarah is an avid reader who loves escaping into new worlds. Sarah spends most of her free time curled up with a book. In the first paragraph, I refer to Sarah as "the bookworm". In the second paragraph, I use pronouns like "she" and "her" to avoid directly repeating Sarah's name. Sarah's favorite genres are fantasy and science fiction. She finds the imagination and creativity in these stories truly inspiring. Lately, she has been enjoying the Harry Potter series. When she's not reading, Sarah enjoys playing soccer. As the goalkeeper on our school team, she takes her position very seriously.
