QFT

While washing hands at the sink.

ME: Do you know that some scientists predict fishes would be extinct by 2030?
FRIEND: Um so?
ME: Can you imagine your grandchildren growing up not eating fish and not knowing what a fish looks like?
FRIEND: Hmm dont care lah. By the way turn off the tap when you're not using please. I want my grandchildren to grow up knowing how water looks like.
