"If any one of them can explain it," said Alice, "I'll give him sixpence. I don't believe there's an atom of meaning in it."
Not everything is explainable, Alice should learn to understand this, especially to those who dream day in and day out, and especially dreaming about mushrooms.
Love at first sight with mushrooms may not happen, but the passion of love will keep burning once started. Alice is simply too young to experience this.
You see, she is still keeping that sixpence in exchanging for mushroom soup with butter, leeks, garlic and thyme.
