Must be nice to be Young

Since I've started working I've become mature and responsible. Instead of squandering very paycheck I have to think ahead (retirement, savings, etc.) I have to budget and plan carefully otherwise I'll end up without anything when I retire. My sister, on the other hand, is still in college and has the mentality of a college student: spend whatever you want now and never think about what you've got to pay for in the future. She recently acquired $600 worth of Tiffany jewelry. O.o Dear god. I can't remember the last time I was willing to spend that much on myself for an out-of-the-blue purchase. *sigh* Sometimes I wish I was still young again =(
