He is a fool who deceives the people who matter most to him when it matters most.
He is also a fool and did not believe in his most important person at the most critical moment.
He loved those days when he acted like a fool and did stupid things and made a mess of his relationships.
And he misunderstood a big fool, so he was also a big fool.
Purpose: When encountering something, be more frank and don't leave any regrets.
