I looked at myself in the mirror and I laughed with happiness! I had broken through the seed skin, and was on my way upward through the earth. Now I began to experiment: For several months I wore long braids (a fashion among black women at the time) made from the hair of Korean women. I loved this. It fulfilled my fantasy of having very long hair and it gave my short, mildly processed (oppressed) hair a chance to grow out.
