When does one become Old?

So, I turned 30 last month, and I honestly didn’t freak out or anything, but then an elderly lady told me that she cried the whole day when she turned 30 and a gal in her 20s asked me how old I am and then apologized for asking when I told her my age. 

Since then I’ve started to wonder about middle age and when one moves from young adult to middle age.  I find that I associate myself with the young married crowd more than with the middle aged group.  I’ve stared to look at the things in life that would qualify you for either group and it’s not looking good for my youth.  We own our own house, we’ve got three kids, my husband has a real grown-up job and hasn’t been in school for probably close to ten years, and I’m in the Relief Society Presidency while he’s in the High Priest group leadership. 

Whether I’m old or young, I think most importantly I’m happy.  I’m happy with where I’m at in life and that’s probably why I still don’t care that I’m 30.
