What is that supposed to mean?

I got a haircut this weekend.  I'd been needing one for quite a while, my hair had really gotten WAY too long.  I don't like my hair to be much past my shoulders, but for the last few months it's been slowly creeping down my back to the point where I officially had long hair.

With our tight budget in mind, I thought, Hey!  I'll just cut it myself!  I know, it sounds crazy now, but at the time, I swear, it made perfect sense.  So I washed and combed my hair and put it up in a ponytail and whacked off about two inches of it.  Again, at the time, this seemed like the most brilliant of plans.  Turns out, it wasn't.  It wasn't the worst haircut I'd ever had, but it wasn't good.  Not good at all.  Luckily I'd only lopped off a couple of inches and had plenty to work with when I went to the salon to get it fixed. 

I ended up with my hair length a couple of inches below my ears with some layers.  Basically the haircut I always get.  I like it just fine.  John says it's cute.  But then, I saw my neighbor this morning and she said to me "Oh, you got your hair cut.  Now you look your age."  Now tell me, what is that supposed to mean?  Do I look older?  Younger?  Better?  Worse?  I mean geez, I'm only 30.  I think I'm at that age where I could probably get away with any haircut and still look 30.  30's not old or young really, so any 'do short of "flock of seagulls" works right?  But still, it bugs me.  What did I look like before if it wasn't 30?
