Uhura:  Mr Spock, you don't have to look busy. Captain Kirk won't be back till tonight.
Spock:  No actually I was just seeing if I could read the caffeine ratio.  I've got an early shift tomorrow and I really don't want to be up all night on my computer three nights in a row.
Sulu:    Do you think the captain will let us stay in orbit for the weekend? 
Uhura:  He was meeting someone tomorrow, so at least one more day I think.
Sulu:   Good, maybe I can buy a book tomorrow.
Spock:  Do you mean the store in the spaceport?  That place is spacious.  I'll go too.
Uhura:  Can I come with, guys?  I hate going to those places alone.
Sulu:  Sure.  Well I'm going on break.  I'll be down in rec for a little while if you need me.  Then you can go Uhura, I'll cover you.  How does one hour sound.
Uhura:  Take your time but don't leave me hanging guys.
