@veron, then how to tell the bookshop aunty/uncle ah?
@acid, its my company dnd. the theme is going back to school.
they know many aunties/uncles are out of size already, so allow
wearing of school PE/cca t-shirts. But I am still young though, so
think I can still wear the uniforms :D
Auntie/Unkers wearing PE/CCA t-shirt plus PE shorts is rather
... ... ... scary 
But it should be a fun theme for the younger gen... A good way
to bond the younger and older gen together becoz of the difference
in the culture and stuff back in school...
Edited: An example would be brushing of teeth in school... The
older generation have told me that they all need to squat by the
longkang to brush teeth (anyone can confirm?) while most of us
have the loooooong sink at the canteen to do brushing...
When u think about it, it's actually quite a good reasoning
behind the theme...
