Back when I was 5, my mother and I visited one of her friends who was in prison. This was back when I lived in Haiti. It was him and 5 other men in their underwear and confined to a tiny cell made for 3 people tops. I don't know if it's different now or if it was this particular prison, but we had to be escorted to right outside his cell to have a conversation - so no actual one on one time. We could barely make out who were were talking to, the cell was so dark - and this was during daytime. When we did see him, I remember being scared because of how skinny he got - like a skeleton- I can't imagine they give prisoners too much food. I don't remember why he was in there or what was said, but damn :( Haitian prison is scary.
2nd memory is seing another family friend in a full body cast after a horrific accident. He was in a coma and we spent a long time just talking to him.
On a cheerful note: my third earliest memory is New Years day 2000, also in Haiti. I woke up and first thing I did was ask my mom for chewing gum. I remember that one especially because it seemed like it was going to be important -- I realized that time was passing and I wanted to remember what happened on New Years day. But I remembered the least significant thing ever- asking my mom for some juicy fruit.
