title: Rails views and nill classes
body: <p>I'm outputting the user's First+Last name by using: <code>=current_user.try(:first_name)+" "+current_user.try(:last_name)</code></p>
  
  <p>However, if they're both nil, I get an error for trying to add a space between two nil values. </p>
  
  <p>What's a better way to handle this issue?? </p>
