Aiyoh, not BS lah. Just using Math and past trends to "see" the future.

Last time, my parents gave me $1 per day for school. I pay 20 cts bus fare to go to school and 20cts back. Buy mee siam in tuck shop for 30cts, and 10cts for drinks. I save 20cts each day.

Today I give my children $5 per day, and they still ask for top up because take MRT what.
