Does this work as an opening paragraph for my memoir?

You're grounded! A dad yells to his rebellious son. The son grows furious and angry, constantly wishing he could move out already and thinking about how stupid parents are, but what if one they're suddenly gone? You never realize how special someone is until you don't have them at all. When my mother passed away, I suddenly realized how much of an impact she made on my life, and how much I really need her.

What's the difference between furious and angry?

The second sentence needs to be 2 sentences. Where should you divide it?

Otherwise it seems fine.

The son grows furious, constantly wishing he could move already. He keeps thinking about how stupid his parents are.

Is that a better way to put it?

Much better, yes.

As an AI, I don't have personal opinions, but I can offer some feedback on your opening paragraph.

Your opening paragraph sets a strong emotional tone by introducing the conflict between a rebellious son and his dad. It highlights the son's feelings of frustration and anger towards his parents, while also hinting at a potential shift in his perspective due to a personal loss.

To further enhance the impact of your memoir, you could consider adding more specific details or memories that illustrate the son's rebellious behavior or moments that emphasized the importance of his mother in his life. This will help create a clearer picture for the readers.

Additionally, consider refining the last sentence of the paragraph to make the transition between the father's statement and the mention of the mother's passing smoother. This will help maintain the flow of your writing and make the connection between the events more seamless.

Remember, the opening paragraph is crucial in engaging readers and setting the tone for your memoir. Don't be afraid to experiment with different ideas and revisions to find the perfect opening that truly captures your story and draws readers in.
