Happy Birthday!! :cheering: :cheering:
First of all, birthday money should never ever ever EVER be spent practically, not on bills, not on groceries, not on "something you need" unless what you need makes you happy giddy and excited!!!
Pretend that the person that gave you the money actually bought you the book...wouldn't that be awesome!!!!
and lastly.... HAPPY BIRTHDAY!!!!! :cheering: :cheering: :cheering:
