In how many ways can 6 girls and 2 boys sit in a row if the 2 boys insist on sitting next to each other?

I don't know if this is right, but here is my take on it. 

 

Since the 2 boys have to sit next to each other, we can just count them as one person. 

 

Now, there are 7 people instead of 8.

 

So, what would you do next?
