Someone's Bittersweet Return

In my current house hold I have a host brother, who I have not met because he is on exchange in the United States...
Though that changes today.
This Tuesday evening my host brother will be returning to Lima from Michigan. He is actually the third Peruvian exchange student to be sent home (though one of the three was later revised and seen to have been preemptive). But he is being sent home for having a girlfriend in the US-which goes against the no dating rules that Rotary defines for a reason. It makes it so much harder to say goodbye, which is funny because now he has to deal with that only much worse because he has to say it about three months early (obviously I should mention the no dating rule also protects from other problems on exchange like pregnancy and alienation from other people-only spending time with your partner it's not to your best advantage, ect).
It's sad to see kids get sent home because no one ever wants to leave and it makes the homecoming bittersweet. Of course everyone is happy to be back home, but not in that fashion and not at that time point. Plus it leaves all the extra time that they should have been on exchange extra and empty.

What this means for me is that today I get a host brother.
I must say I am nervous about it because I had already settled into the concept of my family with him out of the picture. And as a factor of the size of our apartment and his completely free schedule there will be a lot of time sorta thrown together. Hopefully we get along and that his return home goes smoothly. Being back at this point could be rough.
So this evening when his plane comes in, I have a new family dynamic to adjust to and a new brother to meet
