Sounds pretty normal to me, my 10 year old boy won't make a drink for himself, let alone another sibling.
I would never give fresh laundry to my 10 year old, it wouldn't be fresh for long! I put it away in his wardrobe its quicker!
I think 10-14 year old children, do need a lot of reassurance, from parents. I read that girls need to hear from there dads that they look pretty, are 'good looking', or which ever words you prefer.
Is there a bin in the lounge, or wherever she is eating snacks with wrappers, we put bins in these areas, they do use them mostly. Cut down on the snacks on offer!
I remember, i have 2 older dc, that it can seem very strange, a perfectly ordinary item of clothing, can become unwearable, due to some strange system of rules, they pick up by osmosis from school.
I think in terms of what they want, less is more, give less, they will be more grateful when they do receive something, and will ultimately expect less. Those first jobs at 14/15/16 only pay a few pounds an hour, if they have been spoiled they won't want to work for that.
They turn out alright dispite the apparent laziness, my daughter is hardworking now, age 16, makes nice cups of tea etc. It doesn't all have to be achieved at once, another thought, my older son, around 12, went to someone else house, and when i collected hm, they said how polite and helpful he was, they do know how to behave the kids, they just like to relax at home i think!
