Little Keh Poh Chi (KPC)

At one time, my sister did this at home and interestingly, I also do this now. So what did she do years back that I'm also doing the same now?

Whenever I hear our neighbours entering or leaving their units, I will run to our door and look at them. I will also call out to them "aunty" or "uncle" or "bye-bye aunty/uncle"

And then I will go in the house and tell mummy "i bye-bye aunty, uncle"

This can annoy mummy as most times I will immediately run to the door when I'm in the middle of something like eating or when I'm changing.

Mummy wonders when I will start asking them questions like how my sister did.
