Who is old?

Today I was reading Jack a book. This particular book was showing pictures of a little girl growing up and the different stages. I then asked Jack, who he knew who was old? He answered with GG (which is his name for Charles's grandma). I was satisfied with this answer (sorry GG!). Then he starting meddling because he then said that I was old. I was about to get bent out of shape when he then exclaimed that he was old too. How could he think any differently, we are always telling him that he is such a big boy. It just made me realize that age and oldness are in the eyes of the beholder. And in my eyes, I am not old. How about you GG?
