I've been a big sister for about 15 years now, and my little sister has indirectly caused me to think about myriad things. Here are just a few that others can surely relate to.

1. I basically got the beta version of Mom and Dad's parenting, while my little sister gets the release version.

2. I'm supposed to be my sibling's role model, but I'm a mess who has no idea what I'm doing. Surely there's someone more qualified out there.

3. I don't pick on my sister because I hate her, I pick on her because that's my God-given right.

4. It's not that my sibling is babied by my parents, it's just that they are treating me like an adult.

5. I'm told I was originally super excited to have a little sister, I wonder what changed. Like what could my sister have done as a baby or toddler that made me go, "no I'm pretty much done with you."

6. Where's my thank you for not making teachers hate my sister solely on the grounds that we're related?

7. Hypothetically, would I like you more if we were full sisters, or do I only dislike you half as much as I could since we're half sisters?

I wouldn't replace my sister with anyone else in the world, I can't wait to see what else she helps me to realize as we get older. She's slow to get the joke, stubborn and is a little tone-deaf, but she puts up with an overly sarcastic, equally tone-deaf me, and I love her.
