Rosie White was indeed a pretty girl, but Russel Lincoln didn't like her.
It wasn't anything specific, just that he didn't have any feelings for her, and had never even thought about liking her.
Amelia Sanchez talked a lot with Old Lady Turner, and when she left, she exchanged phone numbers with Rosie. Rosie told Amelia her number, and Amelia had Russel input it into his phone.
"Call Miss White so that you don't make a wrong call when you go to the company and can't reach Miss White."
Russel was really obedient, doing whatever Amelia told him to do.
Russel called Rosie on the spot, and Rosie over there answered the phone and noted it down.
Amelia took out her phone: "What's the number, I'll dial it."
