story going another way?

So I was writing last night and as I was working on my story. It had an odd change in it. I was thinking that I was going to go one way with it and now its flipped and kind of going another way. Its interesting way to go. Just not my first idea. I'm letting my self follow this story. I want to see where it takes me. Even if its down a bad story idea. but i did make the 500 words as i also do. thats all for now
