I text you.              

                         Oh good.
                         You text me too.

That's what I said.
I text you.    
              
                         Right.
                         But you text me back.

But how can I text back                 
when I text you first?

                         I text you. Then you
                         text me back.                  

But I text you.

                         Exactly. And then you
                         text me back.

I'm just gonna go to bed.

                         Good idea.
                         You should go to bed too.
