My younger bro lo. That time I was still in primary school and
he used my card to borrow a book. Just before the due date, he lost
that book. And since lost 1 liao then might as well don't return
the other 3 lo. 
What I can't figure out now is that how 4 kiddy fairytale + er tong
jing dian xiao shuo books would add up to $70.
