I am not particularly sad or upset. I'm sad that if I talk to my children about my life as a black South African, growing up under apartheid (I was 16 when NM was elected) I will be describing a great man in the past tense, and that to them, Nelson Mandela won't seem as 'real' as he was when he was alive.
I am not sad or upset he died. He authorised many deaths. He also mourned them, later. One of my friends lost her mother- from one of those terrorist attacks. Strangely enough, as we met in university, if it wasn't for Nelson Mandela, we would never have met, she was white and would have been living a completely opposite life to me.
I am 'glad' in a way that he died as he essentially transformed my adulthood, and the lives of my family and friends, and he didn't deserve to suffer in the way that he was suffering in old age. I'm also glad that many fellow South Afticans are marking his death with singing and dancing, and celebrating his life.
