Time goes too fast!
Here's Isaac, posing in the light of his birthday candles. This was the most human of his birthday pictures. His other poses included "zombie birthday." I'll leave that to your imagination.
I didn't want Isaac to be born on the 13th, because some years, his birthday would fall on Friday the 13th (like this year.) I'm not superstitious about Friday the 13th, but I thought that birthday might provide opportunity for someone to give him a hard time sometime. If that has ever happened, I'm sure Isaac was able to handle it.
