Father's Back

A year since my friend's passing.

From time to time, he has come up to my mind.
He should have been in his families all the time.
Besides, taken care of others.
He is such an attentive person.

Generally sons grow up looking at their father's back.
I am wondering what is his son now looking at.
I would assume sons should learn from their father in some parts and push back in other parts.
As my friend was perfectly a nice person and now is in heaven, it would be hard to push him back.

Though it's personal, I feel sorry for this point, too.
