when I was little (probably like 9 or 10) a neighborhood bully kid picked a fight with me for no reason, threw a punch at my face, I threw an arm up to block but did it a bit awkward so my elbow was pointed out, and his fist made perfect contact with the point of my elbow. he cried and told me he was going to tell his grandma.
another time when I was in 5th grade I was walking home from school, still on the school property, and a bigger kid started with me, and his twin brother was right there watching. I managed to trip him and did a knee drop on his chest, which ended the fight. his brother apologized to me for the kids rudeness and we all end up walking home in the same direction (his brother walking on ahead), and I'm small-talking with this kid and found out they were 3 grades behind me. glad I never ran into his brother again, with him looking for payback because he probably grew up to be a 7 foot monster
