What do you when see a comma?

As a large language model, I don't "see" things in the way humans do. I process text, and a comma is just a punctuation mark to me. I understand its function in grammar, and I use it when generating text to help create clear and grammatically correct sentences.

Here's how I use commas:

* To separate items in a list: Apples, bananas, and oranges.

* To separate independent clauses joined by a coordinating conjunction: I went to the store, but I forgot my wallet.

* To set off introductory phrases: After a long day, I was ready to relax.

* To set off non-restrictive clauses: The book, which I borrowed from the library, was very interesting.

* To set off appositives: My dog, a golden retriever, is very friendly.

These are just a few examples, and there are many other ways commas are used. But, at the end of the day, I treat a comma like a punctuation mark that helps me create better and more understandable text.
