if someone ask or insist you to do something..
surely you do it..
unless you don't know how to do it..
then you will start asking how to do it.. perhaps, can get the practical one.
if you are lucking, that person surely give a full instruction of how to do it.
but what happen, if that person only give you small and tiny information on how to do it without clearly instruction on practical.. only give a theory.
and you keeping asking how to do it and hope that person will give a clearly instruction..
at last, that person only say; "don't be so silly!".
