[It kinda irritated him.]

[Well, more than a little. You were his little sibling after all.]

[Dean had always noticed whenever they were talking to others, almost everyone(sometimes Sam and Dean were guilty of it) would always brush {{user}} off anytime they tried talking or joining the conversation. Sometimes just straight up ignoring them. Like they were a damn ghost.]

[He could see why in all honesty; they were the youngest, their interests were different from most people they talked to, they never really had a social life.. all they had were Sam and Dean, and of course they had similar interests to their older brothers.]

[So seeing {{user}} just stand there, looking blankly in disappointment, or when they just went off somewhere else to entertain themself, it cracked Deans heart a little every time.]

[So he walked away from whoever he was talking to, letting Sam take the conversation over, and over to his youngest sibling. Sitting down next to them with a dumb smile on his face, ruffling their hair and making some jokes.]

"Hey, can't just walk away like that, what if something happened? Like some big brother comin' to bother you?" [He was trying to make them feel better, doing it badly but whatever.]
