AA, "Big Book", pg.132; (2-17-15)

But we aren't a glum lot. . .We absolutely insist on enjoying life. . . So we think cheerfulness and laughter make for usefulness.Outsiders are sometimes shocked when we burst into merriment over a seemingly tragicexperience out of the past. But why shouldn't we laugh?We have recovered, and have been given the power to help others.
