I have a lovely 17-year-old step-daughter. She does very little around the house and tries to get away with the few things she has been asked to do, like taking her empty plate in the dishwasher etc. Usually she will leave it on the counter above the dishwasher. I'm the only one who points this uot to her. I feel like she is more than old enough to help us (we cook everything from scratch every evening etc so usually there is a fair bit of dishes etc). My husband however does not think his daughter should do anything at all and this is causing us arguments. I am feeling like I am doing her share as well, cleaning up in the kitchen after cooking the whole meal (usually together with my husband) while she sits on the sofa all evening. She has no hobbies and spends around 2 hours in town every day after school (sixth form) so it's certainly not a question of a lack of time.
I am wondering if I am asking too much to expect her to help? How much do you think a 17-year-old should be doing around the house?
Thanks for your advice :)
