Rebecca wants to investigate the strange e-mail

"Kelly," Rebecca said, "Meet me at my place. I've got something I need to show you." Kelly misinterpreted Rebecca's distant, preoccupied mind as her being nervous, and was secretly hoping Rebecca had a sexy surprise for her. "Sure! Be there in 15 minutes!" Kelly hung up her phone, and Rebecca followed suit, getting up from her bed and wandering back to her computer to re-examine the e-mail. She was definitely still curious, but if she was going to look into this, she didn't want to go alone, it wasn't safe. And perhaps Kelly would have some information about the strange address. Rebecca thought on the matter as she got up and went to the bathroom to clean herself up before Kelly got there.

About ten minutes later, Rebecca heard the buzzing of her intercom. She ran to her door, pressed the intercom. "Hey Kelly, come on up" Rebecca said, her hand ready to press the door unlock button. However, she didn't hear any reply. She thought that was strange, but the intercom did have a tendency to malfunction sometimes, often for weeks before her landlord would send anyone to fix it. She WAS expecting Kelly, and it was in the middle of the day. What harm could letting anyone in be at this point?
