Blake progressively progresses in the second verse to the "grasshopper" and "Mary and Susan and Emily," the youngsters who will also participate in the singing of the "Ha, Ha, He." The children and grasshopper also emphasize innocence and gladness. Mary and Susan and Emily are described as laughing. The third stanza is about joy and life. Blake calls it his "Dance of Life." He begins with a line derived from Milton: "O life how many things there are that we miss by not seeing them!" Then he describes the dance of life: "A dancer leaping in his tread / Mingles his foot with yours; nor is it dead, but lives again: / For other dancers join the dance, and so on, till the end." This shows that we should not take life too seriously because there is always another day for happiness and joy. In conclusion, Blake says that we should live our life like it's meant for dancing because joy and laughter are part of life.
