This is my little sister (almost 12yrs) Caitlin's Question:
How can I persuade my parents to buy me a MacBook Pro 17"?
I only have 2000HKD and if i give up my pocket money for a year, then I can pay back the money to her but she still wont let me. She thinks I will give up on my laptop after a couple of months, and by the time the school TELLS me i need a laptop, mine will be "out of date"...
