I mean I could totally write a reply to just Cal, and I would have no problem with that.  (It'd be hella' awkward though, with neither of them making any effort at eye contact.)  
But my vague plan for that thread was something like:

• Get some people
• Droog very briefly introduces what they'll be doing and has them pair off
• And then proceeds to sit behind his desk reading a newspaper because ew, children
• So y'all can play out friendships/romance stuff/whatever kinds of interactions you want
• And maybe a small crisis that will force him to actually get up and do something
• (I feel like I may have left this off my app, but he is apathetic to a fault.  He likes not doing things.)

So if anyone else wants to chime in now would be the time.
