Conversation today

Today I had a conversation with our house girl that went like this:
Asha: ".....kazi?" (which i believe meant, why aren't you at work?"
me: "Hapana kazi leo....uh....schulini mama (hmmm can't say died in swahili) anakwenda Mungu HIV/AIDS. Pole. Schulini leo hapana, lakini Wednesday sawa." (no work today....school mother...went to God. Aids. Sorry (sad?). School today no, but wednesday ok.
