title: Why does the number of nodes keep increasing in neo4j even though we don't create any nodes?
body: <p>This is the number of nodes before I create the new one:</p>
  
  <pre><code>neo4j-sh (0)$ match n return n;
  ==&gt; +------------------------------------------------------------------------+
  ==&gt; | n                                                                      |
  ==&gt; +------------------------------------------------------------------------+
  ==&gt; | Node[0]{}                                                              |
  ==&gt; | Node[1]{address:"rioeduardo92@gmail.com",comment:"home",person_id:"1"} |
  ==&gt; | Node[2]{address:"rioeduardo92@yahoo.com",comment:"work",person_id:"1"} |
  ==&gt; | Node[3]{person_id:"1",name:"Rio"}                                      |
  ==&gt; +------------------------------------------------------------------------+
  </code></pre>
  
  <p>after I created the new one, the node that I just created is started from node number 300:</p>
  
  <pre><code>neo4j-sh (0)$ create (n:lolo{color:'blue'}) return n;
  ==&gt; +-------------------------+
  ==&gt; | n                       |
  ==&gt; +-------------------------+
  ==&gt; | Node[300]{color:"blue"} |
  ==&gt; +-------------------------+
  </code></pre>
  
  <p>Thank you</p>
