I live at home with my parents and sister (I'm 21, sister is 19). My parents ask us to pay board unless we are in full-time education; neither of us are in education currently.
I pay the amount my parents request which comes out to around 50% of my income, I save the other quarter and have a quarter left to buy things I need. My sister on the other hand earns around the same as me but on a less consistent basis (her earning fluctuates week-by-week but it averages out to be equal to mine). However, as soon as she gets paid she spends it all straight away on clothes, getting her nails done, takeaways, etc. She left sixth form in June and has worked since and I don't think she has once paid any money to my parents.
I feel so resentful answering the door to her latest ASOS parcel or Nandos delivery day after day. When she runs out of money she asks my parents for money which they give with no expectation to pay them back - e.g. for meals out with friends, etc.
I know there is a maturity difference between 19 and 21 so I am not sure if I am being unreasonable by feeling so resentful... I am saving money so that I can move out next year but it's taking forever.
I also want to emphasise that I have no problem paying board. I am grateful to my parents for letting me live at home still and I think I almost feel guilty too so I make sure I am as helpful as I can be around the house too. It is knowing how differently my sister is treated that is frustrating me but I don't know if I should just ignore it as she's only 19?
