YOU GUYYYSSS! Can y'all just always stay like this?  I'm sure it's a combination of your personalities and the fact that you aren't close in age, but you guys drive each other crazy 99% of the time. Mostly, it's a pain in the butt having to say "Stop messing with your sister."

But, it's all about the 1% that you do. Those tiny glimpses of " I NEED my sister" that I know that you will always have each other's backs.

Protect each other. 
Love each each. 
BE there for each other. 
Always. 

And a bonus, look how much you've grown in 3 years!
