To answer the original question........
I was the youngest Soror in my former grad chapter for a couple years. It was NOT EASY. Many of the women were much older but thank goodness I had the opportunity to get to know them EXTREMELY well. I never felt handheld or babied in my Recording Secretary position. No one ever questioned my ability. It was the programming ideas that were hard to implement as a younger Soror. The hardest part was there were hardly any young Sorors in the chapter and our level of involvement differed.
In my new chapter, things are much different. It's MUCH larger and there are more younger Sorors (now younger than me, for a change). Balance of ages was EXTREMELY important when I transferred (due to relocation). In my current position, I do feel handheld by certain people due to my age (or should I say....the age they THINK I am <we age well....don't we
>). But so far, so good.
