Watching from the outside

So pretty much I feel like an outsider. (at my dads) I have been heree for almost three weeks cause it is summer and i stay here half the summer.. But anyways my dads doesnt let me do any chores or help any around the house... But yet i can help with my liltle sister and brother (2) yes twins. any time.. awilst my stepmother is sleeping.. Her mother witch has known me for a whole 6 years called me Ashley today.. Isn't that great.. And they went and got a family portrat with out me.. Nice dad real nice.. I feel like a visitor.. amongst other things.. What should I do ?
