"Your still you..."

I thought a lot about this today. Turning 28 and two more years till 30 I thought a lot about if I was still the same person. If I was to run into an old friend would they say I'm total oposite when they knew me way back or would they say your still you? I use to hate macs, now I have an apperication for them. My shopping habits went from mall shopping to wal-mart. I'd like to say I've gotten wiser, but I still can't balance a checkbook. Music taste have expanded and rap is still bleh. Time flies and this is my day...
