I don’t know why it became the ‘default’ good bye phrase, but it did. It probably anoys you because you’re ‘an uptight white guy.’ I’m an old, fat, not terribly uptight white guy anymore. Part of that is because when you focus on what’s important and are sincerely searching, I believe you find that it’s easier to ‘let go’ and be honest about what’s happening. It’s also important to be sincere. I don’t say ‘have a nice day’ if I don’t mean it. Many times I say ‘make it a nice day’ because i believe it’s up to us as to what happens … so ‘make’ it happen.
