I am actually an extrovert. My personality type is an ENFP. Pretty much to a t. In fact I have been called the epitome of an ENFP.
As for social interactions, well I am very versatile. While I only have a handful of very close friends I consider myself rather social. I am at ease with large groups and one on one interactions. Where do I thrive? With intimate groups. 5-6 friends. A dinner party, or a girls night, beers on the LES. Or a karaoke group in Cape May on the beach. I also enjoy one on one time with a close friend. Reading together, making dinner, curling up on the couch to watch Sabrina with Audrey Hepburn, or Bronson with Tom Hardy. Exploring new cities is best with someone who understands you. I like large groups of like-minded people gathering. I like bringing people I love together. But, I also like meeting new people.
I enjoy alone time. Especially eating lunch on a bench in the city or by the shore. Going to the movies alone. Museums are sometimes best explored alone.
I hope this answers your question.
