What if my parents don't go to parent conference?

so we have parent conferences next friday,im in middle school grade 8. i dont want to show the confenec sheet to my mom or dad because my teachers all pretty much hate me..as usual. for talking and i REALLY dont want to get grounded before hallowen,and whatever with "stop talking then" answers,i realize that i should stop. but i was wondering do they contact parents if your parents dont show up? and not everyone in the cl has to go to the meeting,just the ones that misbehave in cl. thanks
