FOUND THE DEVICE..

While they were done eating and was about to left Tina felt someone was staring at her... she was looking at her back from time to time..

Laura asked, " what is happening to you Tina...?"

Tina shook her head. "No, not that ..., but I'm getting more and more confused. I feel like I've been followed.. someone is keep tracking me..."

After saying this, she could not help shivering: "don't you think that no matter who that person is, it's abnormal?"

Laura looked at her with some worry: "playing chess with such a person, you can't think about it with normal people's thinking, maybe she is abnormal."

"Will you stop scaring me like that?" said Tina

Laura said while teasing her.., "didn't you scare yourself first?"

"You're so unfriendly," Tina said as she scoffed..

Laura couldn't help laughing: "OK, I'm more friendly. I'm really afraid of you. Let's think about it. I think there must be something to find out .."
