HELP: I am searching for a quote to gift to my father

[SlappySalmon]

My fathers birthday is coming up soon, and I was hoping to give him a framed picture of him and his sons, along with a quote that he once mentioned that he found meaningful.

It was something along the lines of: Fenton Hardy had never forgotten what his boyhood was like, so he was a good father.

I have searched for a long time, but have been unable to find it. I assume that it is in one of the earlier books, so I was hoping that someone may be familiar with it and could point me in the right direction? Thanks
