What being a father figure means

Last December, Cyril, the son to our youngest sister came to live with us. He is roughly my daughter’s age mate. His parent’s marriage was on the rocks and when my baby sister could not take the abuse anymore, she upped and left.

We had always been in constant communication, but she did not let the cat out of the bag. 
One midnight last December, she called my younger brother, who also lives in Nairobi, and told him that she and her son were on the bus on their way to the capital city.
“We’re in Nakuru,” she said, “I’m bringing my son so you can live with him as I’ve found work in Riruta Estate.”
