The birthday party on Saturday went smoothly, and Mr. Jiao's purpose was achieved, as many people privately assured him they would take care of Jiao Ma and the two kids when he went abroad.
After a busy day, the Jiao family of four planned to rest well on Sunday. However, Zheng Tan wasn't included in this.
Zheng Tan slept all afternoon on Saturday; he didn't help with the birthday party and didn't bother interacting with the annoying kids. He just slept, ate, and drank until the party ended, then went home to continue sleeping. Therefore, unlike the other four Jiao family members, Zheng Tan awoke feeling quite energetic the next morning.
The Jiao family didn't eat their first meal until noon on Sunday, sleeping through breakfast. After lunch, Zheng Tan went out to play.
The campus was sparsely populated on the weekend, with people sunbathing, dating, and jogging everywhere. After ignoring the seventh student who meowed at him, Zheng Tan decided to take a walk off-campus instead.
