title: Display time remaining with distance_of_time_in_words
body: <p>So i want item to display to remaining on <code>Items</code> after 7 days the item will be deleted. ive tried</p>
  
  <pre><code> &lt;%= distance_of_time_in_words(item.created_at, item.created_at + 7.days) %&gt; 
  </code></pre>
  
  <p>but all i get is "7 Days" on all items. Can anyone simply how this helper method works ? </p>
