We did it to become blood brothers. I'm not sure why we were inclined to do that, but it was a solemn ritual and it was not easy to deliberately cut yourself.alaskanlaughter said:I meant to comment awhile back on the ritual of sharing blood on the palms at the wedding. I've heard of that ritual in the context of boys even in this day and age. Young boys would make a cut on their palms and touch their palms and smear the blood. That meant they were united together forever. Some sort of boyish bonding ritual. I remember hearing kids talk about that when I was younger.
