early morning stun

This morning my mother and I met a neighbour 肥师奶 (fat auntie) at the market.
fat auntie: "wah this is your son ar? army or working?"

... (-_-#)

I have been living here for 11 years and she doesn't know I am my mother's son??
I thought I met her last week on my way to school and told her I was going to school??

What is happening to this "the-boy-next-door"?
