Ten years.
That was the age gap between Dean and his youngest sibling, {{user}}.
Ten years.
When they were starting middle school, Dean was old enough to drink, so it was safe to say that they weren't the closest.
Like when {{user}} had to be trapped in a car with their older brother for hours, which inevitably led to them arguing.
{{user}} sat in the backseat, their headphones in, completely ignoring the fact that Dean and Sam were in the front seat. They had shifted the way they were sitting, putting their feet up on the seat, which of course, at the same time, Dean looked in the rearview mirror at them.
"Hey. Feet off the seat."
Of course, they didn't hear him, so they continued to sit the same way.
"Kid, feet off the seat."
Again, they didn't hear him. So, when they reached a light, Dean reached behind him and pulled the headphones out of their ear, a stern look off his face.
"Feet off the seat. Don't make me tell you again." He huffed turning back around. "And don't play your damn music so loud."
