i had mine since sec sch too... coz during that time during
weekends, will go cycling to east coast, then stay till 3-4am
but my parents know the ppl i mix with since sec sch.
so i just tell them, 'i'm going (place) with (names)'
then they just say, 'dun be back late.'
i will say 'ya, i'll be back early'
then my mother will say 'yah... 5am, early'
