Molly spread the invitation on the café table as if it were a map to buried treasure. It was pink, glittery, and smelled faintly of cupcakes. Bill leaned over it with the solemnity of a surgeon. “Four o’clock,” Molly said. “Community hall. Birthday girl: Poppy. Theme: princesses and dinosaurs.” Bill frowned. “That’s two themes. Reckless family. Unstable.” “Focus. There’ll be presents stacked higher than your unpaid parking fines.” “I told you, those fines were a misunderstanding. The meter and I had different philosophies.” Molly tapped the invitation. “We go in, we blend, we acquire the goods.” Bill looked down at his black turtleneck. “Blend how? I look like a sad mime.” “That’s why I got costumes.” From beneath the table, she produced two crinkly plastic bags. Bill pulled out a glittering purple cape and a foam triceratops head. “No,” he said. “Yes.” “I am not wearing the dinosaur.” “You are absolutely wearing the dinosaur. I’m the fairy godmother.” Bill examined the triceratops head. One horn drooped sadly to the left. “Why do I always have to be the creature?” “Because last time you were the magician, you panicked and made the rabbit worse.” “The rabbit was already judgmental.” A waitress passed, saw the glitter, and kept walking. Molly lowered her voice. “We enter with confidence. Children accept anything if it arrives carrying balloons.” “Do we have balloons?” “No. I have a bag of inflated surgical gloves.” Bill stared. “That is not the same thing.” “It’s whimsical.” “It’s a poultry nightmare.” Molly ignored him and sketched a square on a napkin. “Presents here. Cake here. Parents here, pretending juice boxes aren’t stressful. We’ll create a distraction.” Bill brightened. “I can sneeze in the dinosaur head.” “You can not sneeze in the dinosaur head.” “I can sneeze very dramatically.” “You can hand out the glove-balloons.” “And then?” “And then I wheel the presents out on a trolley.” Bill glanced around. “Where do we get a trolley?” Molly paused. “We improvise.” “That is what you said before the goat incident.” “The goat incident had charm.” “The goat ate a policeman’s hat.” “And everyone loved it.” Bill slumped back. Outside, a bus hissed at the curb. A child in a paper crown passed the café window, dragging a parent with one hand and clutching a wrapped box with the other. The box was lumpy, badly taped, and decorated with three stickers and a heroic amount of love. Bill watched them go. “Molly,” he said, quieter, “what if the presents are rubbish?” “They’re presents. Rubbish is irrelevant.” “What if one is just a mug that says Best Dad, but the dad cries anyway?” Molly folded the invitation, but not as sharply as before. “We’re professionals, Bill.” “We once stole a cheese wheel and returned it because it looked lonely.” “It had character.” “It had a face drawn on it.” Molly sighed. The glitter on the invitation stuck to her fingers, sparkling accusingly. “Fine. Adjustment to plan.” Bill lifted the dinosaur head hopefully. “We steal the cake?” “We do not steal the cake.” “The magician?” “No.” “The bouncy castle?” “How would we even fence a bouncy castle?” Bill considered. “Slowly.” Molly pushed the cape toward him. “We attend the party.” “As thieves?” “As entertainers.” Bill blinked. “We are not entertainers.” “We’re disasters. Children adore disasters.” He looked at the drooping triceratops horn, then at Molly’s stern fairy wings. “And the presents?” Molly stood, gathering the glove-balloons. “We guard them.” Bill smiled. “From criminals?” “From amateurs.”
