I just got back from a state park with cliffs. My fingers are tired, and I have scratches all over. I also fell off a cliff into a river

DAMN!
I would go hiking at parks but my brother hates walking and can hardly walk a mile and a half, last time i went walking with him and some cousins he kept on arguing and acting like he got shot in the chest just because he walked less than 2 miles.

Damn, I've walked over 10 miles before without resting
And if your brother REALLY was truly tired from walking, he wouldn't have energy to argue in the first place, it sounds like an overreaction to me

YES he really overreacts, (he is older than me lol) and then he started telling my oldest brother and my cousins that i was being a jerk for no reason, (i told him to quit complaining) then my oldest then started calling me a douche bag and a dick. (I ain't even do nothing)
