There are so many reasons that I love my sister. But seriously, who wouldn't love a sister like this...
If you need a meal, she'll kill it for you.
If you need to discuss national or international affairs, she's your girl.
If you need someone to be silly with, there's no question that Erin is the right choice.
The first two pictures just cracked me up so I had to share. Plus, I just really love my sister.
