text: Mariah: Abe?
  David: Why not, he is chill
  Mariah: I will write to him. Or ask the flight attendant girl?
  Carlos: They are both fine by me. But if it will be the "flight attendant", make a new group :D People can see older messages after joining
  Mariah: Uff, thanks for letting me know. So whom do you prefer?
  David: It makes no difference. You are the group leader, lead us :D
  Mariah: Ok, I wrote to Abe, we will see what he says
  Carlos: The professor just said that we can have 4-5 people since we are a large class. Take both of them?
  Mariah: Why not, I will write to her as well :)
target: Mariah, David and Carlos need another group member. They can have 4-5 people in the group, so Mariah, who is the group leader, will ask both Abe and the flight attendant girl to join.
