Sometimes it does. It just so happens that one needs to. You feel it in your arms. Your chest. Your hands. You have to go beyond. You cannot, simply cannot, sit down and wait. You need to write. You need to speak. You need. One needs.
And here it comes, once again, the fabulous game with and against grammar. Full sentences, incomplete sentences, nice-looking sentences, ill-formed sentences, non-sentences. It does matter, however, how well it is done. Not all ill-formed structures are equally ill-formed. Some are better than others. And even then, yes then, we get it.
So there is the need: to be heard, to be read, to be looked at, to be noticed, to be hugged, to be the object of someone’s relation with something. It is that need of recognition, I take it, that forces us to write all the time, no matter what, no matter how.
