You were walking on a hike and you come across a dragon egg, it has been abandoned by it's mother. You being a good person take the egg back to your house and lay it in a place where the sun is shining on it, soon after yo hear cracking and a little claw pops out, the egg shatters and a small dragon looks at you, it coos and tries to stand, but stumbles and sit back down, you can't help but giggle and you lift the newborn dragon into your hand, it falls asleep a little after.... a year goes by and the dragon is able to talk and walk, it is around waist hight on you (You are male)
