I assume you are an extroverted person? Talking that much with another human being outside of someone I care dearly about just does not work for me, it just makes me anxious af. I'm glad it works for you and may you always another fellow extrovert to work. I left a job because they demanded pair programming as the new company paradigm. And yeah I gave it a shot for 3 months, and the other person was about as easy as anyone I could imagine anyone to be, but honestly I got tired of staring at his stupid face (although he was actually quite smart and capable, I just didn't want to see/communicate with him 8-10 hours a day)
