I may have to remember it in the event my parents 
find out what I spent on Yahoo Japan.  But I don't 
live with them anymore, so hopefully they won't 
find out.

As for hiding the receipts--that is a big no-no.  
Do it if you have to until the cel comes but keep 
it somewhere *safe* (e.g., inside a plastic baggie 
after you've swallowed it) and then shred them!  
It's the only way to prevent extinction in case 
you're discovered.  And let me give you a 
hint--the car is not a good place.

Good luck.
