8 Telltale Signs Your Cousin Is Your Truest Soul Sister Out Of All Your Friends

Your school plays, your sweet 16 bash, and your high school graduation — these are all major milestones that your cousin has attended. It helps that you are family, but she would be there for you no matter what. You've been supporting each other since you were in diapers, and you'll keep supporting each other.

When you open your phone to call someone, your fingers just start dialing your cousin's number without you even thinking about it — it just comes so naturally. You text each other and send funny Gifs all the time, so when you're upset, you immediately call her. She's basically like your emergency contact, and will be there in a heartbeat.

Every time you hang out, you end up laughing so hard it literally hurts. Sometimes, you're even in tears because you and your cuz are honestly hilarious AF. It must be those genes, because you share the same sense of humor. It has allowed you two to have endless inside jokes that, to this day, still crack you up.

Some people only see their cousins for family events, but you can't wait for Grandma's birthday to see your favorite person again. You hang out all the time — whether it's hitting up a new spot for weekend brunch, or just chilling after work gossiping over some wine. You're probably hanging out right now, or at least have plans to see each other later this week.

The perks of having known someone your whole life is that you really know them. Your cousin knew every secret crush you had in high school, because you confided them all in her. She also knows you were the one who broke Grandma's lamp, but that's a secret she'll take to the grave.

Quite honestly, your cousin could write a tell-all book with the dirt she has on you. But, you trust her so much that you know your secrets are safely locked up, and she threw away the key.

Finding the perfect travel partner is actually a very difficult task. You might want someone who's interested in scoping out the same sites as you, and someone who's down for the adventure.

You and your cousin have been going on family vacays for years, so not only are you experts on traveling together, but you also know you already have the perfect go-to travel buddy. She's the first person you think of when the wanderlust takes over, and you want to travel to all of the dreamy places on your bucket list.

You know each other so well, that you don't even have to say full sentences to understand what the other is saying. You have a special cousin language that many are envious of. It's probably why you're so good at charades together.

This is the plus side of being family. No matter where you end up or how many times you get into a fight, you will always have your family there for you. Your cousin isn't going anywhere, and when you're BFFs with her, you know you are best friends for life.
