Just to keep things fictional, Kevyn is the older brother who was born in November 1987, and he was among the top of his high school's Class of 2006, whereas Kathryn is the younger sister who was born in October 1991, and she was among the top of her high school's Class of 2010.

To separate fact from fiction, this is way unlike the real me, who was born in November 1992 and was 19 when I graduated from high school in 2012, although I was originally part of the Class of 2011 until midway through high school (most likely 10th Grade). Therefore, that makes her my slightly older sister. I still go by Kevyn in real life, but I'm still separating the real Kevyn (b. 1992) from the fake Kevyn (b. 1987), regardless.
