title: If (var !="String") is always true
body: <p>When I ask from user and input, it always falls in the loop even if it is the right input or not:</p>
  
  <pre><code>Console.WriteLine("Μήπως σκέφτηκες το " + n);
  answr = Console.ReadLine();
  while (answr != "N" || answr != "Y")
  {
      Console.WriteLine("Δεν μπορώ να καταλάβω την απάτηση σου. Ξαναπροσπάθησε: ");
      answr = Console.ReadLine();
  }
  </code></pre>
