5 going on 20

The last day of summer for the kids. Eli starts kindergarten tomorrow, not sure I'm ready for this. I started thinking - OMG, he's 5 which is 1/2 way to ten which will be 1/2 way to 20...He is a 1/4 of the way there!...then I came back from my thoughts and said he has only been here 5 years...wow, how my life has changed in 5 years! :-)
