You always have one or two boys around you, from whom u dont know what theyre really looking for... they happen just to wanna be your friends. It could also be a person of your gender. And in both cases, sometime you can get surprised when they reveal their deepest feelings. For sure, if he or she has ever expressed openly profound dislike for one aspect of your being and you know his/her dark side, but you still hold on each other - like, say, old school mates - then, I think, you could call him a good good friend, whitout fearing any trassgressing of those limits...
