As the oldest sibling in the house, you wear a lot of different hats: assistant, chauffeur and sous chef. Whenever your siblings need something, they know who to call. Here are the true signs you're the oldest sibling.

1. You've driven to practice.

You've been to all the different car lines, band practice pick-up, and tennis pick -up. You always go in the right direction and park in the same spot as your mom does.

2. You know exactly what to buy from the food store.

You enter the food store like a boss. You're ready for action and can recall your mother's food list, including each specific brand from memory.

3. You've mastered Mom's spaghetti sauce.

That's right, after years of devouring the perfectly made spaghetti sauce, you learned how to make it. You can make it all by yourself in a pinch and no one notices a slight difference.

4. You remember everything.

Addresses, holidays, birthdays and random childhood memories. If someone needs a phone number ASAP, you're much faster than scrolling through contacts on an iPhone. You always make sure your siblings never forget your parents' birthdays.

5. You were the guinea pig.

Expectations always seemed higher for you because you went through all of your major life events first. You definitely waited until you were 13 years old to see your first PG-13 movie, and at 22 you text your parents to let them know you're in your apartment safe and sound at the end of the day.

6. You're the go-to crafter.

When Mom's busy and your brothers have a last-minute school project to do, they know you'll be there with your glue gun and crayons at the ready.

7. You can recite every line to the "Froggy" books.

"'FROGGY!' called his mother." You loved reading your youngest brother bedtime stories and can still remember all of the famous lines.

8. You're Daddy's little girl and Mommy's BFF.

The bond between you and your parents is extremely tight, because they know they can always depend on you and you know you can always depend on them. And sometimes they feel bad that you're the guinea pig but hey, you have to set the bar high for the young 'uns.
