Ok so it so it was friday and we got done with the talks test and everything...And my friend said this group which is this guy, im friends with but not close. and these 2 girls, one im not enimeies with but not friends either...and the other one (the girl i had the fight with) shes not my friends but she will tell me kaitlin your so pretty i love how you do your hair and blah blah and then talk mess bout me and try and start stuff with me. well my friend i told yall bout in the beggining said that that group (the one i told yall bout) said that he said that this other boy was two faced...and i told the group no he never said that i was with him mostly all day. and that girl (i had the fight with) says "(my friends name) are you talking bout me when she clearly knows were not cuz shes right beside us hearing out conversation. my friend says i dont even know you. and i respectfully said that we were talking bout (his name)" and she tells me "btch was i talking to you!" and i told her i respetfully told you we were talking bout "his name" and then thats when my friends break us up. after that day she didnt do anything to me...im honestly not scared of her at all. im going to stay out of drama as much as i can cuz its the end of the school year and im ready for summer(: but i honestly want to know what yall think on this girl and minor fight. and any advice because it keeps on playing in my mind and ugh i want it out!! idk why but everytime something bad happens to me or somebody else...it always plays in my mind and i hate it. but anyway thanks soo much(:
