Not exactly a great story. I would have given it 3 stars except for the whole weird phone relationship being just too implausable. I assume the author set the story in 1977 to avoid pesky things like *69 that would have made it simple for her to trace Vinnie's number and destroy the whole premise of the story. You wonder where the parents are because they talk every night at midnight, but never once does a parent overhear the phone ring or interrupt their child chatting in the wee hours.
However, the whole initial set of phone calls was just too bone-deep strange. He calls her at midnight, hangs up, mumbles thru a 2nd call, and then tells her "I want to f*ck you." What would any normal, rational teenage girl do when some pervert wakes her up in the middle of the night and says he wants to f*ck her? Either call the cops or at least tell the parental units that some freak-with-feet is harassing her. So what does she do; she keeps answering the phone and talking with him every night. Because I'm sure she knows from the beginning it's not a rapist on the other end of the phone line, just the geeky kid from across the street who watches her undress from his window.
