Well I have this enormous crush on this amazingly beautiful and talented girl named mary(or Mary catherine,marebear,Mary potter or baby girldepends on which one I feel like calling her that day,but normally just Mary or baby girl)she's also one of my best fiends(it kinda funny they way we became friends,we were both sitting in the hall way durning 9th period,she was finishing a test from the day before and I got kicked outta class cuz I feel asleep on my desk,so we were sitting across from each other so we got bored and we got to talking and throwing a bounce ball back and forth,then I accidently hit her in the mouth with the ball and she got a bloodly lip so I walked her down to the nurse,we've been friends ever since ) anyway I really like her but her dad hates me,hes meet me a couple times before,and according to her he doesn't like the music I listen to(but it's the same as the music Mary listens to),he doesn't like that I play bass(umm idk what that has to do with anything)doesn't like Im atheist,doesn't like that I wear band t shirts(how seriously how does wearing a Ramones shirt make me the Antichrist or something) but so does Mary,the only things I think he has a good reason for hating about me if that I can have "anger magegment issues" I got into 2 fights last year and Mary told her dad about them(I guess he's choices to ignore the part wear in the 1st fight a kid pushed Mary into a locker and when I told him off later he punched me first and the second fight this jerk made Mary cry cuz he was calling her names like emo and slut(Mary's had 4 boyfriends since 6th grade(we are going into 9th btw) what a whore(sarcasm) and was making fun of how Mary cuts herself(she's gettin better) so I just snapped and punched him in the jaw) but still that's just like 1 thing,I still don't get the bass thingbut I still want him to like me,what If me and Mary want to go out and her dad won't let us :/ I mean her mom LOVES me(like seriously she's told me that me and mary should go out atleast 3 times) her older sister bekah loves me just as much as her mom,even Mary's dog loves me(by all dogs love me) but her dad hates me how do I get him to like me(or atleast not hate me so much)
