That rule applies to chicks. If youre tight with your bros it shouldnt be a big deal. If theres three people it means theres generally a neutral force that can help solve issues between the two others. If you guys are some drama queens obviously its going to be an issue regardless of friend or not.
Better to be with your bros then some weird pygmy kid that jerks it while he watches you sleep
