Dear Mandy，
Pm not doing well in my lessons at school，especial in maths. My dad says I must try hard
because he wants me go to university. He thinks I'm lazy，but it's not true. I work really hard，
often study late into the night！I've tried to talk to my mother，but she always said I have to work
as hard like my brother does. My brother doesn't study very hard，and he always gets excellent
grades. It's not fair！
The only thing I like it is art. My teacher says rm the best student she's had for year. When
I told my dad，all he said was，“You mustn't waste your time in art. You must focus your mind
on your lessons！”Pm feeling quite puzzling what to do now．Would you please help me out?
Thanks a lot！
Yours sincerely，
Lisa
