Dear Holly,

I took nearly 500 pictures of our family on vacation this past week in Oregon.
Surprisingly, in one of them, I was able to capture a glimpse of your brother tolerating your affection, in the form of you hanging onto his arm.
Though his body language appeared somewhat detached, the fact that he allowed you to cling onto him was basically the equivalent of him actually saying out loud:
“I love you, too.”
I have watched for the past few years how you have officially longed for his approval.
Looks like you’re getting there.
Love,
Daddy
