My sister is not very good with money and over the years my parents have given/lent her quite a lot in small amounts. My Dm recently lent me some for school uniforms and let me use her c.card to buy some Xmas presents. Every week without fail I have paid her £10 a week and will carry on until the debt is paid. Now in the past 2 months my Mum has brought my sister a washing machine and freezer both of which were to be paid back at around the same amount. She has paid nothing and my Mum has said she has written off her debt! My sister(in her 30's) is married,works but doesn't have a high income just as I don't. I can't help feeling this is unfair should I say something to either of them or just suck it up as I have in the past? The latest thing is that she is going to spend around £100 on her ds for Xmas.
