Quoted from RonB:
Now I just wish my 13yr. old son would have the same interest as you do.
So my dad would have said the same thing when I was 13. All I wanted to do was play with our IBM PS/2 computer instead of play ball or work on the house like my dad did. I ended up becoming a computer programmer. I think the world would be pretty boring if everyone's kids were just carbon copies of their dad's interests! Having said that its totally cool that at a young age this kid is tinkering.
