Something you didn't know about me.
Nobody in my family knows my mum's birthdate. Somehow her birth records were lost and the authorities only listed the month and year, but left out the day. My mum thinks her birthday is 1 January cos that's the default date for everyone who's lost their birth records, but strangely her birth month wasn't registered as January. Anyway, this resulted in us not celebrating mum's birthday, and mum's vagueness about my bro and my birthdays (I guess it's harder to remember other people's birthdays when you don't have one yourself).
