Suming quickly explained, "He's a homeless man I met while working. He had no place to call home and seemed so pitiful, so I found him a job at the zoo. He doesn't have a family, and had nowhere to go for the New Year, so I brought him home with me."
"You and your dad were cut from the same cloth when he was young, always nosing into other people's business!" Mrs. Su said a bit worriedly.
Any parent who hears that their son has taken in a vagrant will not first think to praise him for his kindness and willingness to help, but rather worry about safety issues.
Only those who have no stake in the matter would openly praise Suming for his kind heart and such.
