One, potentially. I may know an ENTP as well, but I'm not very good at determining types without the assistance of a test. I like them both quite a lot, though I don't talk to them much. But I do enjoy being around them and hearing what they have to say. They're very interesting people, but the potential ENTP can be quite irritating at times. He enjoys invading my personal space, making me squirm. He used to have a habit of stealing my phone and going through it. He doesn't do this anymore, but it's still in the back of my mind.
