Long story short, my 18 year old step daughter of 12 years does nothing, no job no education and doesnt lift a finger around the house. I have 3 other children and another step daughter. They all have their chores i.e unload dishwasher, sweep floor help clean table and they all do it. Thier ages are 4, 5, 6 and 12 they all do there bit, but my 18 year old has not done nothing in over two years. I stopped doing her washing 4 months ago cause i never even got a thank you. She does nothing me and her dad have tried our hardest to support her but she has been so disrespectful and also bullies her younger siblings. I cook our children thier dinner earlier than mine and thier dads and often we offered to her she said "i will eat it later" and then it would go to waste and she would never clean her plate. So now i dont dish her up a plate, i always cook extra anyways but as i dont put it on a plate for her she will cook herself noodles and then go eat her room which she knows she isint aloud to do as she caused a mice problem last year. And as she knows she isint aloud she waits for me and her dad to go to bed. So im sorry if its too much but am i being unreasonable to stop doing her dinners?
