once I saw an phip/indo(balck skin, not tsure) bringing two girls playing in park.
she only sat on the chair without stay beside the girls but shout so lound to the girls in cantonese:
"don't xxxx....don't xxx..."
while I was thinking how dare she was,
suddenly I heard the girls call her
''mami''.
you never know, maybe she is really the boy's mother.
