music, cool clothes, অথবা আপনি could save it for something big. Go shopping at your fave stores and if আপনি see something আপনি like, go for it. Your mom probably wants আপনি to spend it on your birthday.
Hold onto it until something really cool is out and আপনি want it. আপনি don't want to look back and say "Wow, I had 55 dollars, I could've used it on that"
CD's অথবা iTunes. When আপনি find a song that has a good beat and good sound, there's nothing better than that. I reccomend Panic at the Disco and My Chemical Romance.
Get a DSi XL! It's a DSi but it's BIG! অথবা for DS, a game called Scribble Knots! আপনি can write in anything (some stuff won't work)and it comes up on the screen! আপনি play as a boy named Maxwell, and he can kill the things আপনি make! It's so fun! Oh, and Happy Birthday!That's a pic of a cute সীল on its back! হাঃ হাঃ হাঃ so cute!
I don't know your preferences, but I know I'd buy manga. I প্রণয় me some good manga. I'd probably get some One Piece, Ouran High School Host Club, DNAngel, InuYasha, and Naruto. Then I'd only have 5 bucks left, but I would be very satisfied with my new purchases. (I recommend getting your TokyoPop পছন্দ before it closes it's American branch. Just sayin'.)
