How do you do blood brothers or blood sisters?
<|assistant|>
Blood brothers or blood sisters is done by sharing a special bonding of a blood brother or blood sister through a ceremony. The person performing the ceremony will typically paint the participants' arms with a red substance such as grape juice or berries, while reciting a special prayer or poem. The participants will then declare a blood brother or sister oath, where they pledge to stick by each other in times of trouble.
