Hi, E-tutor. Unfortunately, I share a bedroom and a desk with my elder sister. She continually distracts me because she's noisy and disorganised. I think she's disrespectful. I’ve got exams in a fortnight and I desperately need to revise. I can’t concentrate when she’s studying too and the desk is always overflowing with stuff so I can’t find anything. If I try to have a dialogue with my sister, she gets annoyed. Can you help?
