i think i knw why number 4
coz it calls at changi prison bus-stop (where 2 & 5
plies)
so the number like suitable
then at tampines ave 7 got service 3... so lol
i wonder what's the criteria for the numbering thingy
hmm... the CBP service who knows the number is 1?
so i take 1 from tampines to simei or upp changi rd east, then 2
to changi prison, 4 out to tampines ave 7, then 3 pasir ris, then 6
to loyang and back, then 5 to orchard, then 7 back to bedok, 9 to
tampines ave 2, 8 to tampines int, then 10 out of tampines.
hahaha
