She's so grumpy.
And we just seem to not get on any more.
If I try to help her with anything, homework/ practise/ any organisation tasks she just gets really aggressive and defensive. I only mean to help her not criticise but it always gets taken as an insult.
Then it usually starts an argument. She's only polite to me when she wants something (sweets/money/Internet access)
Where an I going wrong???
