Is 'Hey' Rude?

In terms of addressing someone, the answer is yes. While 'Hey' serves as a casual greeting, it might not be the most appropriate way to directly address an individual. However, in everyday conversation, 'Hey' is a perfectly acceptable informal greeting, especially in spoken contexts. If you're composing a message in a business setting, it's advisable to opt for 'Hi' instead, as it conveys a more professional tone.
