I've run out of languages but hey, my point is: Why does that sound so much less young than 21?
This may be the first time it won't take me half the year to remember that my age has changed, with all that's happened the past year or so, not to mention actually graduating, 21 just didn't seem grown up enough to cover how much I've learned all of a sudden.
It's also the last of those legal landmark ages, until I hit retirement.
Lets wait and see how I handle 25 (quarter of a century: makes a girl think...) and 30 though. If I start contemplating plastic surgery, somebody please shoot me.
