This is *so* true.
This line was very moving. It reminded me of when my husband and I were younger, and we used to take our children fishing. We haven‘t done so in quite a few years, but now our younger son takes his own children fishing. We are presently that “older generation” of which the author writes, although his dad in this book was very much older than we are now. And yet...those are much beloved memories of special times together.
