It was a lovely day. A sweet little family was sitting at the dining table, discussing something. Summer, the daughter of the family, said, "Now I finally have holidays, so why don’t we go on a trip?"

"But where should we go?" Dad asked.

Kai, who was scrolling through his phone, found a spot. "What about this one: 'The Treasure Museum'?"

"Where is it?" Dad asked.

"Hmm, it's about 3 kilometers away from our home," said Kai. Dad looked at Summer for an answer.

"Yep, we should go there," Summer said.

A few days later:

We booked a room at a hotel near the Treasure Museum. We decided to visit the museum in the evening.

It was lovely. We saw so many things: ancient language inscriptions, pictures, artifacts, and more. We explored the whole museum. Later, we learned there was an event behind the museum, so we decided to check it out after we finished inside. By the time we left the museum, it was already night. We walked behind the museum and found many shops and tents where we could buy various items we had seen in the museum. Mom and Summer bought some accessories, and it was wonderful visiting the shops and tents by the beautiful beach at night. Later, we played on the beach, losing track of time. Before we knew it, it was already midnight, and all the shops and tents were closed.

Summer spotted a lighted tent shop far away from the beach. "Should we go there? We didn’t check out that tent shop."

"I think we should. Don’t we?" Kai asked Mom and Dad.

"No, it’s already midnight. We’ll go tomorrow," Mom and Dad said.

"Okay," Summer said sadly.

"Stop making that face. Didn’t Mom and Dad say we’ll go tomorrow?" Kai teased.

"Hmm," Summer responded sadly.

Kai pinched Summer’s cheeks. "Stop pinching my cheeks!" Summer exclaimed.

Kai pinched harder. "Ouch! Stop it, KAI!"

Kai finally released his grip. "What did you call him?" Mom asked, a little angry.

"I mean 'brother,'" Summer said quietly to Mom.

Kai smirked. "Say sorry to your brother, Summer."

Kai’s smirk widened teasingly. Summer, annoyed, said, "But Mom, he pinched my cheeks really hard!"

"Still, apologize for calling him by his name. He’s older than you, Summer," Mom said.

"... Sorry… Brother…" Summer said reluctantly.

"What did you say?"

"S.O.R.R.Y. B.R.O.T.H.E.R. Can’t you hear?" Summer snapped.

"I can’t hear you because you’re saying it so quietly. Say it again," Kai smirked.

"SORRY, BROTHER! Loud enough for you?" Summer shouted.

"Oww... okay, okay, I hear it," Kai said, rubbing his ears.

"And I hate you. Mom is always on his side," Summer pouted.

"I can’t help it, he’s my sweet boy," Mom chuckled, adding, "But you're my lovely daughter too."

"I don’t believe it," Summer pouted again.

Mom kissed Summer on the cheek. "You have to believe it, whether you like it or not."

"Did you all finish fighting or not? The mosquitoes are eating me alive!" Dad complained.

"We should head back to the hotel and rest in our room," Dad said.

"Same here," Kai agreed.

"Then why are we waiting? Let’s go," Mom said
