In the 1970ies, I listened to this Cat Stevens song. Then I was the son, and I remember clinging to every word of this song and find the advice, then live with it. It touched me.
Now, having completed most of my fathering, I know that my son and daughter are there and they have figured out that there is something going on.
When I clung to every word as the son then, I cling to them as the father now, and I must admit that Cat Stevens was brilliant. Every word in the song has deep meaning that spans generations.
