I am an introvert

Though I can be social one on one and in small groups, I need time by myself to recharge. I can go to festivals and outdoor markets with artisans selling their wares among other places but I do not have to interact with everyone around me. I can simply walk around and observe. If something interests me and I feel comfortable I can get quite talkative and this is where people might mistake me for an extrovert. I’m a more social introvert almost an ambivert. I am an infp or infj. But my function stacks say infp somewhat more.
