I had grown up in brutal poverty, and saw touch as a privilege for those with less traumatic backgrounds. Then a friend and mentor changed my life

Welcome to the Guardian’s Power of Touch series

It happened one day during my first year of college at Rutgers University, in my home state of New Jersey. The anti-apartheid movement was raging on my college campus, there was still a massive buzz about Jesse Jackson’s first run for president and I had instantly become woke, as we say, because of names such as Winnie and Nelson Mandela, because of the Aids and crack epidemics, and because of my adopted big sister on campus, an older student named Lisa Williamson, who would later become the famed activist and bestselling author Sister Souljah.

For sure, Lisa was one of the most incredible speakers I had ever heard. She was a fearless leader, and I became so instantly fond of her, I even called her “Ma” just like I did my own mother. And she adored me, taught me and shared with me everything that she knew and was learning, in real time.
