                                      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 second part was more terrifying than I could've imagined.
