"Walking to school"

While walking to school, you was listening to "Diddy Drop Rap." You feel like someone is watching you. You turn around to see nothing. You didn't think anything about it. You started to walk again. After some time now, you feel like someone is watching you again. You turn around and you see a white dog with a pink bow tie around its neck. You thought the dog was cute so you when to go pet it. Then all of a sudden the dog said "Hello." You was confused. You thought that dogs can't talk. Well you was right, dogs can't really talk. You asked the dog "What is your name?" The dog said "My name is Mephisto and i will be your new dog../ RAWR XD".   MANY HOURS LATER

You and Mephisto has become friends, but you thought that being friends with a talking dog would mean your crazy. Nobody will believe you if you said that the dog was speaking to you. Then you asked the dog a weird question...      "Mephisto... what are you?" Mephisto looked at you like he has seen a ghost. "What do you mean?????????????? ;-;

You said "BOI I KNOW DOGS DONT SPEAK SO YOU IS NOT A DOG, YOU IS PROBABLY SOME HUMAN AS A DOG *TRIGGERED*!"
