[huxley]

1. "But she's right ( ) where would I go?"

2."Boy ( ) you must be lost."

3."Oh, one more thing ( ) can you cook?"

4."Of course, but first ( ) you see ( ) I was hoping for some sort of reward for my troubles."

5. "Yeah! They took her ( ) and it's all your fault."

6."You'd better change your attitude ( ) or your friends will never show up."

7."When they come back ( ) they' re going to know it's us."

8. "Are you going to let us through ( ) or do I have to call the police?"

9."Hey, you can laugh about this tomorrow ( ) but right now ( ) we need to leave."

10."Sometimes( ) but at least I tried."

It looks a bit like homework to me, Hux. What are your guesses? (Hint: I myself would use a few dashes,colons or semicolons, too.)
