title: program stopped working (if a number isn't typed)
body: <pre><code>Console.Write("\n\nHow many seats do you want to reserve?\n");
  int numSeatReserveLucy = int.Parse(Console.ReadLine());
  </code></pre>
  
  <p>thats the part in my code i want to be fail safe. it works fine... IF you press numbers... but if you press a letter, then the program stops working .. showing many wierd things before i close the program.
  what code is it i need to get it to say like: "sorry thats not a number"
  and then roll back so you can continue where you pressed wrong.</p>
  
  <p>it should be fairly but i dont remember how to. </p>
