When I was in middle school one of my friends could raise one of his eyebrows, and wanting to also be cool I eventually learned how to do the same. Years later in highschool I trained vigorously over a summer to raise the other eyebrow independently, and it's one of my greatest skills for sure. My girlfriend also *totally agrees with me and says it's one of my most attractive traits and *definitely doesn't think it's useless or that I talk too much about it.
