backstory; i broke up with my gf a few months ago and she fucking hates me. she's got a new bf and we've both moved on but she's bitter as fuck. also, i tend to quietly sing lines from songs i'm listening to when i get lost in music and have nothing to say. 

i went into town with a few friends just to sit about as it was an alright day and we had nothing else to do. we were sat on a bench in the park talking about things and just enjoying the weekend. i was listening to i should have known by foo fighters, i got lost in the song, closed my eyes and sang one of the lyrics.

"i was inside of you"

i'm not sure why but it was just the part of the song i was at and i wanted to sing. apparently i sang it a lot louder than i thought i had. next thing i know there's a fist flying at my face. turns out my ex was walking past with her new bf and he heard me say really loudly "i was inside of you." he got pissed (we've had a few shouting matches over dumb shit) and decided this was the day he was going to actually make his move.

my friends got super pissed at him and shoved him off me before he could land another blow and after about 5 minutes of shouting he fucked off. my friends sat, bitched about him, asked me if i was okay and when i explained they burst out into laughter. needless to say i don't think i'll be singing in public anymore.
