As long as there are children (and emotionally-stunted adults), there will always be bullies, just like there will always come a day when someone stands up to them—like this 12-year-old named Ava and her pink invitation to her sister's bullies. Written in the classic grade-school medium of magic marker on construction paper, the "invite" looks like it should be for a pool party, but it's full of weapons-grade sass. It kindly asks an unnamed "you" along with her lackeys Elke, Grace, and Ashley to "stop being jerks to my sister." The note makes no threats as to what might happen, but given how viral this has already gone, I wouldn't mess with Ava (full text below).
