I agree with Matt on this, why do you need to conjure up a massive story behind a shot simply liking what you see and capturing it is a good enough reason for me which a lot of purists would deem as simply a record shot. However if you have explored all the angles thought about DOF, exposure compensation, chose a focus point, found foreground interest, composed using the rule of thirds or even deliberately breaking that rule etc then you have had a vision of what you want to capture so already there is a story behind the image.
I guess there is one thing sharing an image with familly and friends to sharing it with the public whether that is in a newspaper or exhibition, I can't help feeling that some people try to look to deeply into photographs sometimes there is no harm in doing so but if you don't find anything step back and appreciate it for what it is. I recently took a sunset which was published in our local rag after all almost everyone likes a good sunset and the wow factor of a nicely captured daily occurance is enough for the majority.
Having said that one of the main reasons I do the comps is I find it helps to imagine an idea and workout how I am going to shoot the image from an idea so once again there is a story forming so I believe simply I liked it is a good summary but the thought process behind why you liked it and how you captured it is a story in itself.
I seem to have gone full circle here
