He says his kid asked for programming books. Doesn't seem like it's being forced to me. Could it be that maybe, just maybe, both father and son enjoy programming?
You may be right, but I wanted to share an anecdote anyway.
When I was 8 years old, my dad offered to buy me a go-kart. I think he was concerned I spent too much time indoors, and wanted surprise me with an exciting idea. I knew that my dad didn't have a lot of money, and I also knew he'd be angry if he bought the go-kart and I never used it, so I lied and said I didn't want one.
My point is that there's often more going on inside children's brains than we realize, even at a young age. The kid could be asking for that present because he thinks it will make his father happy, for example. Just something to think about.
