Aww Megan, we went thru this with my oldest niece. She left a few weeks back to move to Missouri for college. It's so sad to say goodbye but you are still excited for their new adventure.
Its funny thing about brothers..... As much you want to choke them at times, you love them all the same
Big hugs for you! And think of this as a plus for you.... maybe he will bring home some college hunks during his breaks
Another plus of having an older brother
