So, I'm not sure where this came from, but earlier today, I wound up getting a headache (obviously that's not what I was referring to, heh), and I had to go lie down. Now, I'm the type of person to imagine comforting thoughts to help myself sleep, so my mind went to work and thought of one sweet thought - 

How awesome would it be to become Shining Armor's BBLBF (Big Bro-Little Bro Forever)? Now, I don't mean it in the sense of replacing the BBBFF role with Shining and Twilight, but how could would it be to have somepony so protective be your mutual big brother? A protector under protection by a special Unicorn captain of the Royal Guard. It's..to me, it's such a sweet thought.
