In her third appearance, a tight-capped Addie delivers Max's present but explains that she can't come to his party. Good friend that he is, he tactfully ferrets out the reason (she's embarrassed by her new haircut), gets her on the road to recovery (``Your hair is growing back!'' and ``You have more hair than I do''), and, best, agrees to wear the jungle suit she's just given him if she wears hers to the party, too—thus concealing her newly shorn locks. Robins's wryly sympathetic voice and comically realistic dialogue are right on target; as always, Truesdell captures the histrionics in a few deft pen lines decked out in cheerful color. A particularly amiable take on a lively friendship. (Easy reader. 4-8)
