I recently got caught in an argument whirlwind after my Younger Brother got in trouble, and in another argument when my brother was talking about how all adults lie, and how he didn't do anything wrong, even though he got in trouble now. I know he's saying all of this bullshit because he's mad, and I'd do the same because hey. Been there, Sheen that. But him saying that all adults were lying to our mother, and how he didn't do anything bad? That pisses me off a lot, and I can't express my frustration at how whiny my little brother is. I'll admit, I am a dick, I sometimes don't think twice, and I do get angry and say some things or do something that I know I'll get in trouble for, but if he keeps lying in front me and my mother's face, you bet we're gonna have an issue. We already toned down a little, but it's a matter of time before everything erupts like a Supervolcano. What do I do?
