who?

got experience before?
... got sms from someone which you had given your number to, but can't remember who? =p
especially sometimes when you met someone in a rush, you gave them your number and ask them to either miss call or sms you,
then only receive the sms a few days later
by then, me cannot remember who is who liao, might have asked a few people to do same thing within that few days ...
me think next time better ask people give me their numbers, then me miss call them or sms them =)
