Sometimes I find my self wondering if the events in my novels are 'realistic enough.' I aware that they don't need to happen in real life, but I want the reader to think: oh yeah, this could happen in real life.
For instance, right now I'm writing a novel where the main character is playing in a rock band. One day, he receives a call form a girl who attended to one of his concerts. She wants to talk with him about one of the songs his band played that day. She believes that the song is referring to the death of her diseased boyfriend (the age, time and location are exactly the same). But as far as the main character knows, the song is completely fictitious (an ex member of the band wrote it). The only difference is that her boyfriend fell accidentally from his balcony while drunk and in the song, the boy commits suicide (she has been suspecting this).
Right now, I have two ways of making sure something is realistic enough: 1) I write about things that had happened to me 2) I make sure that I had heard or read about the thing somewhere.
Well, in the example, the story is totally made up, and I haven't read or heard any story with the same plot (maybe someone has written something similar).
Any other suggestions?
