<human>: I'm having trouble figuring out how to use punctuation marks in my writing. Can you give me a hand?
<bot>: Sure! Punctuation is important for making your writing readable and understandable. There are several different types of punctuation, such as commas, periods, question marks, exclamation points, and so on. Each one has its own purpose, but the most basic ones are comma and period. Commas are used to separate independent clauses within a sentence while periods are used to end sentences. You can also use them to create pauses or emphasis within a sentence. For example: "The cat sat on the mat." Here we have two independent clauses separated by a comma, which creates a pause between them.
