<human>: I'm having trouble figuring out how to use punctuation marks in my writing. Can you give me a hand?
<bot>: Sure! I can help with that. Punctuation is used to separate words and phrases, as well as to indicate the end of a sentence or thought. There are many different types of punctuation marks, such as periods, commas, semicolons, colons, question marks, exclamation points, and parentheses. Each one has its own purpose and function, so it's important to learn when each one should be used. For example, a period indicates the end of a sentence, while a comma separates clauses within a sentence. Learning the rules for using punctuation correctly will make your writing more clear and effective.
