For eleven years he sat at the same corner of Cairo Road. Nobody knew his name. Traders walked past him. Commuters stepped around him. Children gave him a wide berth.
Then a Remember Me volunteer asked him one question: "What is your name?"
His name was Joseph. He had a wife and three children in Mpika. He had lost contact after falling ill. It took the team three weeks to reunite him with his family.
This is what it means to remember someone. Not with pity, but with presence.
