Yea I feel you OP. For some reason something animalistic wakes up inside me when I hear a stupid screaming child (or anyone screaming) and I just want to grab it by the leg and slam it in the ground till its head cracks open and fling it as far as I can. Or just run and curb stomp it.
I don't know why, I think kids are adorable, I wanna be a father and have 3 kids, but screaming just triggers something in me.
Other things that make me go full blown retard rage are: >Tv static >Lags>Bug flying close to my head>Loud people>Liberals and "I care for the planet vegetarians" and tree huggers
