You know what, I really envy that.
I don't have any children. But my friend has a son, about the same age (10 years?), and he often takes him on walks through the woods and teaches him stuff. That must be just about the best feeling in the world. For both father (parent) and child. I know if my dad had taken me out and shown me things like that I'd have bloody loved it and it would have left me buzzing for years.
I'm going to get my girlfriend pregnant now, just so I can have a son and take him out and do things like that.
Maybe not.
