Well, I’ve got this down to a [i]science[/i]. Your dominant hand goes over their corresponding shoulder, while your non-dominant hand goes under their corresponding arm. For instance, if you’re right-handed, your right hand will go over their left shoulder and your left hand will go under their right arm. Fair warning: this tip only works when both people are of the same dominant hand. For cases where both persons have opposite dominant hands, agreeing on a method of hugging before attempting the hug is recommended so as to avoid that awkward moment when you’re not sure how to hug this person. However, if this is unavailable, then the next best option is for each person to start the hug with only one arm at first, so as to figure out who reaches over versus under, then once that dilemma is solved, continue the hug with both arms.
