Hey @Sprouting_Flowers, much like yourself and the others who have already replied, I can heavily relate to this. I'd like to think I'm a pretty even mix of introverted and extroverted, very much depending on the people I am with and my energy levels.
I agree with @snazzy_pigeon in regards to quiet people also being very observant. When I'm in my 'introverted' mood and I am being quiet, I find my mind stops racing and I can focus on every little thing my friends tell me. And I actually surprise myself by remembering these random things that they tell me and they appreciate that I remember these things because they know that I care for their friendship and listen to the little details.
Never think you have to change for everybody. People may not like being quiet and shy, but if that is what makes you comfortable, never see it as a bad thing. You should never have to adapt to anyone elses needs and be someone you are not.
