You are being stubborn today because someone has rubbed you the wrong way and not as a result of your response to them really being justified. It doesn't matter to you what the reasoning is behind the action on your part. Instead of changing your behavior, go with the feeling until it doesn't suit your needs anymore. It is a better learning experience to stand firm rather than cave because it is not appropriate according to what others may think.
Gemini is mental energy. They are intellectual, forever youthful and strong communicators. Geminis know something about everything and excel when they can put their versatility into action. Good luck trying to get one up on a Gemini. They will make you look foolish so don't even waste your time. A Gemini is forever restless; they have to read and make enquiries. They also love to talk and will always have something witty to say.
