Maria: Where are you? On the way?
Kate: I'm leaving home soon(-ish)
Matt: I'm still having dinner with Josh
Jenny: I'm preparing to leave
Maria: no! And I'm already on the subway. This is annoying
Maria: whenever we fix a certain time to meet I'm the only one to take it seriously
Josh: hahaha, poor good Maria
Maria: don't be sarcastic!
Josh: we've finished the dinner and I promise we will be there before you
Maria: that would be nice 
Maria's frustrated because Kate, Matt, Jenny and Josh don't take their meeting seriously.
