What the fuck?

In the previous chapter, we read that Mr and Mrs. Henry decided to adopt Robin too and we read the reasons behind this decision of adoption. Then the warden let them to Michael and Mike so they could decide themselves. On this Robin whispered into Robert's ears:

Robin: Respectful, hmm! They don't know the meaning of respect

After a while of talking between Mr. and Mrs. Henry, the warden and the kids, and after seeing their grades, the Warden announced:

Warden: Mr. and Mrs. Henry decided to adopt three kids namely Robert, Robin and...

Everyone was breathless to hear those words:

Warden: ... Mike

Michael: What the fuck? (shouted)

Warden: What is wrong with you Michael?

Michael: Nothing Mam!

Warden: Okay kids go to your rooms and pack your bags and the rest of you go continue your routine.
