Here is a revised version with corrections:

"Please review the following information regarding our recent consignment: The Hamour fillet and Cream Dory fillet did not freeze properly, resulting in both items changing color and becoming rotten. Upon delivery to our outlet, the Cream Dory and Hamour fillets were rejected due to the damage. Therefore, we regret to inform you that we will be deducting the full shipment amount."

Ah, the joys of having a little sister who's a big baby! As for your question about punctuation, I am pleased to enlighten you. Semicolons are indeed used in compound sentences to join two independent clauses, but in your case, we don't have two separate clauses. Thus, the punctuation in your statement can be improved. Here's a humorous suggestion:

"My little sister is a big baby; she cries all the time... for attention, food, toys, and even when she gets a speck of dirt on her pinky finger!"

Remember, punctuation is essential, but a dash of humor goes a long way too!

Great question! In this case, the punctuation is not used correctly. Compound sentences are indeed connected with a comma, not a semicolon. A semicolon is used to join two independent clauses (complete sentences) that are closely related in meaning.

To correct the punctuation in your sentence, you could use a comma instead of the semicolon. It would look like this: "My little sister is a big baby, she cries all the time."

However, it's worth noting that starting a sentence with "she" after a comma could make the sentence sound more informal. If you prefer a more formal tone, you could rephrase it as two separate sentences like this: "My little sister is a big baby. She cries all the time."

So, to summarize, compound sentences should be connected with a comma, not a semicolon.
