8 and a half years.
Dear Jack,
You are one lucky kid. Last week, you got to spend 5 days of summer camp at the Nashville Zoo!
It was especially cool since you got to spend that time alongside your friend Duncan, who you have known since before you were born:
We were in birthing class with his parents back in 2010 when then two of you were still in the womb!
Needless to say, you had such a great time that we’ve already decided to send you back again next year.
Not to mention, your sister is already saying she wants to go in a few years once she is old enough!
Love,
Daddy
