Creepers are not evil monsters, in fact, they are happy campers. Creepers look at you and shake with excitement before exploding out of happiness. So they accidently kill you sometimes or ruin your house. But it's ok because you have unlimited lives in Minecraft. So don't get mad at  creepers! Just make sure they get nowhere near you or kill them if you have to. Haven't you ever been so excited you could blow up? :D
