would be better if this drive is done in Nov/Dec
put leaflets into the mboxes in HDB estates
tell the residents tt there will be a group of ppl coming round to
collect textbooks on this date this date
they can pack and leave at the door or some collection point at the
void deck
must give them time to pack lah

bo? auntie probably still in her pyjamas, hair not combed,
breakfast haben eat... where got time to entertain u?
