My mum told me something funny jus now. She said she met a mad woman at wrk. A 40+ auntie came and ordered 2 packs of fried kway teow from her. After ordering, my mum straight away cook for her. Tat auntie went off to the mama shop beside the coffee shop to buy drinks. When she came back, my mum say to her "xiao jie, ur fried kway teow." She replied"lao chee bye already, still called xiao jie!" (pointing to her private part at the same time). After saying that, she slapped my mum. My mum was so angry that she picked up her slipper and slapped the woman back. Then the woman started going crazy, throwing the bottles of drink she bought and scolding bad words as she left the place.
Moral of the story is: Don't call an old woman xiao jie or else u will be slapped.
