my dad hit me once when i brought home a bad report card it was last year he hit meonce and i whent down and drew the nife i always keep on mt(5 inch switch blade) he didnt see me draw it so he stratled me and tried to hit me again so i cut all the way down his arm he needed 168 stitches...since then he hasnt touched me hes all peachy maybe because he sees me practice my knife throwing and weilding along with boxing he never apologized either but i didnt expect him to after collage i dont plan on ever seein him again but he'll remember me he has a nice scar that goes from shoulder to thumb
