What is the difference between "absolutely" and "of course"?

Native speaker’s answer

"Absolutely" is used to accept something, and to mean "yes" without a doubt. It implies that you are very enthusiastic or excited about something, and it is stronger than "of course". Ex: A: Would you like some water? B: Absolutely! "Of course" is less enthusiastic than "absolutely", and often implies that your answer is obvious and should be known by everyone. It can have a different nuance depending on the tone. With a lower, more sarcastic tone of voice, it can sound rude. However, with a higher-pitched tone of voice, it can be used politely. Ex: A: Do you think this is a good outfit? B: Of course.
