Even though the conversation has dried up - they are now discussing the weather - he continues. The goal is to learn more with every single thing that is said. Do away with platitudes and discussing other's flaws. That is not knowledge. It is infinitely better to learn about where to buy the cheapest shoes (online). Inevitably there will be malapropisms, and spoonerisms will undoubtedly arise too. The goal is to keep trying to avoid those mistakes. But keep talking. Not one iota of knowledge gained can be proven to be completely worthless. Who knows when it will come in handy?
Keep talking bro.
