Everyone’s different, you sound like you may loathe this person, but regardless work is not recreation. If needless social interactions are impacting your ability to work, consider talking to your supervisor. Speaking directly to your coworker may offend, exacerbating the issue for you. Give your supervisor an opportunity to resolve it, who should have more experience and/or training in dealing with conflict.
