                                      When they were talking about Chica and her being killed, I immediately hugged my dog and said to myself, “If someone killed my dog, I would just stab them in the heart 76 times till they bleed out. I don’t care about evidence.” :)

                                                I was at homecoming and sucked on a helium balloon. That night traumatized me because I passed out IN THE GYM and bit through my lip, got stitches, and chipped one tooth and dislocated the other

                                                  The first part was what I've come to expect from Unus Annus.
                                                  The second part was more terrifying than I could've imagined.
