Aren't I too old for this?

So on Tuesday I discovered I had chicken pox. . .at the age of 28 :) As one of my friends from school asked, how did you not get it in kindergarden like the rest of us? I wish. I always thought I was immune because I never had them when all my friends had them and we were exposed at the same times. My daughter is vaccinated against them and had no symptoms when the little guy at daycare had them a few weeks ago. The good news is I don't really have that many; probably 2 dozen and then are pretty concentrated so you only see a few if you look at me really hard--and those sort of look like bad acnce! Plus, they don't all itch like crazy, only a few are driving me crazy. The final straw is that I found I had them once I had traveled 600 miles from home! But that's a whole other story. . .
