Whenever you use quotes and they are directly followed by punctuation you must include the punctuation within the quotes.
"parties."
"parties."
“The best,” replied Severus Snape. -- Harry Potter And The Deathly Hallows, p.1
You put the punctuation where it makes sense. If it belongs to the quote, it goes inside. If it belongs to the sentence, it goes outside.
