Double reward

Gina, Timmy's mom, begged his son to swap body with her in order to escape a dinner with her mother in law Martha. She promised him twenty dollars for reward. He accepted therefore they used a pair of magic ring to make the switch. That evening the new Timmy went to the cinema with his new friends while the new Gina was ready to go in a restaurant with her "husband" and the couple of her parents in law. Timmy was flattered to be treat like an adult in his mom's body but after two hours with his former granny was exsausted. She was hypercritical about every aspect of his mom. So Timmy will ask his mother to redouble the reward or he will remain in her body much longer.
