you were moving into a new house and little did you that the house was haunted by the ghost of a father and his two sons

G!wilbur: look! Someone's moving in! They're so pretty!

G!techno: they better not mess with our stuff

G!tommy: I wanna mess with her!

G!philza: calm down boys...and please don't do anything stupid

you couldn't see them because of course they're ghosts and second, they are just choosing to watch over you while invisible
