I can't believe Sarah and JP are siblings since siblings ususally do not go along very well especially when they are in their youth ( I know I am saying this as if I am not in my youth).

Well, my brother and I are quite fine, but we don't hug as SJP and JP do, not only because hugging is a quite strange notion in Korea particularly if it is between two boys but also because we never meet. He's fortunately coming to the graduation and I will try to hug him. Iam pretty sure it's going to be very awkward. If you have seen the movie "the step brothers'', my brother and I may look like Mike Farrell and his real younger brother uncouthly hugging each other at the end of the movie.
