Am I really this old??

I know I'm not old, but sometimes I just feel like it.  It's more that time has flown so fast!  For the most part I'm very glad with how old I am, but sometimes things happen that just make me feel old.  This weekend was one of those.  It was Brad's birthday on Saturday so we wanted to go out and our family babysitters were all busy...what to do?  I always babysat when I was in my early teens and I they trusted me with their kids...but now here I am with the kids and needing someone to watch them.  How can it be?  Am I really that old?  We found a wonderful girl to come and watch the boys for a few hours.  I drove to pick her up...it seems like just yesterday I was the one being picked up...I remember feeling very awkward and nervous driving with the parents.  It went perfectly fine...Levi was in bed already and Ben didn't even care that we had left him.  He was climbing the couch and licking the wall when we left...oblivious to us leaving.  And we had a wonderful evening...and we'll definitely be doing that again!
