Deal or No deal

Were at Lego shop. Saw something I like but I never ask for it. Mummy knew it when she saw me admiring at it (she can read my mind :p)

Mummy ask : You like it ?
me : Yes, I like to have it.
M : You want mummy to buy for you ?
m : if you want, then you buy.
M : You really want mummy to buy ?
m : err… if can, I would like to have it.
M : Ok, I will buy for you but you must promises to pass your piano test.
m : then dun want la…..
M : You sure you dun want ?
m : What if I can’t pass ?
M : I’ll buy, but you can only open it after your piano test.
m : ok, I’ll open after my piano test.
M : But you have to pass before you could open it.
m : argh…. What if I cannot pass? I dun want anymore :(
M : Is ok if you can’t pass, but you must try.
M : If you never try, how would you know you can't pass ?
m : ok, I’ll try....

It's a deal, I will try my best for the coming test : )
