I'm such a grownup:
I'm in an investment phase. I'm throwing money at stocks and IRAs like nobody's business (and dont' have to think twice about blowing $170 on a flight to San Francisco to see She & Him at Oysterfest). I'm also going through a horrible shopping phase, but unlike my last bouts with shopping addiction, I'm investing in pieces. Amazing sunglasses and gorgeous purses--I'm putting my money into My Favorite Things. Because I love my things, and they own me completely, but I'm way in the black so I'm rationalizing this every which way but up, but MY GOD I NEED THESE SUNGLASSES.
