Little Sister Learns The Hard Way Why You Don't Sleep With The Car Window Open

#1 This is 15-Year-Old Mia Simper hanging out with her young sister, Ella, who's only 6-years-old.

#2 Mia was just driving back home for her family's lake house, while her sister was sitting in the backseat.

It's important to note that Mia was chomping away on some sunflower seeds while this was going on.

#3 After miles of spitting sunflower seed shells out the window, and after Simper's family stopped the car, Mia turned around to see this.

#4 Poor Ella was covered in saliva-laced sunflower seed shells.

Mia said in interview that "I didn't know my sister's window was open or that the seeds were flying back into her face but it was really funny."

#5 Mia posted the hilarious photos to Twitter, where they received thousands of retweets and likes.

#6 And, of course, the internet delighted in this girl's sleeping, oblivious misery.

#7 And people pointed out that Ella was basically them.

But all little siblings out there know the struggle. Even when your older brother or sister isn't trying to sh*t all over you, they inevitably to. Their subconscious minds go out of their way to spite you.

Hopefully Ella will learn to sleep with the car window closed from now on.
