Most Helpful Guy
95% of the time, guys with like hobbies/interests (even when they're closest of friends) keep their talks limited to those hobbies/interests. At least in my own experience.
Most Helpful Girl
From my experience hanging out with guys whenever I was in high school, they do talk about girls, but they also talk about who they'd rather bang, their rank on the banging scale, etc rather than who they have crushes on. lol
