Raelle was getting on her car to leave for work when her phone's ringtone caught her attention. But her phone was not in her hand. She turned her head and found Shui Xian holding her phone.

"You should change your lock screen photo," suggested Raelle. "So that we stop mixing up our phones like this."

"I have a better idea," replied Shui Xian. 

Raelle took the phone from him and attended the call while she still talked to Shui Xian, "And what exactly is that better idea?"

"I'll tell you when I'm done with it," was Shui Xian's mysterious response.

But Raelle was never curious enough to dig into it so she just waved at him, "Have a good day, Hubby!"

"Oh, I'll definitely have a good day," said Shui Xian certainly.

Raelle sat inside the car and finally spoke in the speaker of her phone, "Why so quiet, Hyson?"
