1. You throw each other under the bus by mentioning certain things in front of mom.
Let's be real, if mom ever gave you chores to finish before she got home not everything would get done. Then you would bribe each other not to tell (either actually bribing or a tell and I'll pound you kind of bribing). What fun would that kind of leverage be if you didn't make each other sweat a little?
2. From an early age, they try to make you love the same things they love.
My brother always played basketball, so needless to say I ended up playing a few years myself. I was TERRIBLE. But, because of my brother I had a beautiful shot... that is if I ever got the ball... (I also quit before high school if that tells you anything).
3. When they had to drive you anywhere they hated it.
First, my brother got his license so he wouldn't have to ride the bus with his kid sister. Then he proceeded to think of any reason he could not to drive me. Ah, good times.
4. Mom made you tag along with them and their friends.
This wasn't super often for me, but when it was hanging out with your older brother's friends can be just as painful for you as for them.
5. They can pick on you, but literally no one else can.
No explanation needed.
6. They were always jealous of the "little sibling" card.
Ever had a moment where you were left home alone and you did something wrong? Then mom came home and yelled at your older brother for letting you/encouraging you to do it? And you got away without anything but a "don't do that again"? Little Sibling Card at work.
7. You know the exact thing to say to infuriate them.
Much like how only they can pick on you, you both know the exact things to say to make each other mad beyond belief. This is saved for special occasions.
8. Calling shotgun was a strongly enforced rule.
No one ever wants to sit in the back seat. And while your older brother may think this privilege is for him only, the shotgun rule can never be disputed.
9. They got nicer as you both grew up.
Fun fact, older brothers can actually be kind of cool sometimes.
