My friend sent me a talk about "the last straw". Is there a moral?

There is a proverb in English that originated in the Arab world. It is called "the last straw to break the camel's back", which means "the last straw to break the camel's back".

The straw has no weight. No one will put straw in his eyes. But if you pile straw on the camel's back one by one, one straw will eventually crush the camel's back.

No matter how small the weight is, it can add up to a mountain. This is similar to dripping water wears away the stone and an ant nest breaks its banks. Different from this proverb, it emphasizes: Never add the last straw.
