I'm someone who generally don't know my neighbours. It's easier to just go into the house and not bother about small talk. Then one day I saw a FB post where someone was asking about delivery charges to my area. And a second person had asked to share as she was in the same area. So I put up my hand as well. Then that second person messaged me if I was in this food whatsapp group. Turns out this group was right in my 'taman'!
Woohoo! My area isn't a central one like PJ or Puchong so delivery would normally cost a bomb. So sharing with others was the perfect solution.
