title: discord bot waiting for message
body: <p>So as the title suggests I'm trying to make my bot respond to a certain message. So after a user sends an image, it'll respond with a compliment, then if the user RESPONDS TO THAT MESSAGE with a message such as "thanks" the bot will then go on to respond with a different message, but I'm trying to make it respond to multiple versions of "thanks" using if statements. This is the code so far: </p>
  
  <pre><code>if '.png' in message.content or '.jpg' in message.content or '.jpeg' in message.content:
              await bot.send_message(message.channel, "woah, very nice!")
              msg = await bot.wait_for_message(author=message.author)
              if msg:
                  if msg.content == 'thanks':
                      print("test") 
                      await bot.send_message(message.channel, "hey, gotta compliment nice images right?")
  </code></pre>
  
  <p>i'm not sure if I'm doing this right, the python shell doesn't print test and the the bot doesn't respond in the server.</p>
