This letter is very short sighted. In my case, as a young boy one of the first things I ever constructed on my own was my love of fishing. I remember catching a grasshopper and using it for bait and within just a few seconds of tossing it in the creek behind my house. I don't recall the outcome, but the excitement was all it took to make me determined to be a fisherman.
I then saved up my meager allowance (earned from doing chores) until I had enough to send off for the brand new Zebco spincast rod and reel combo that was advertised in a magazine I had.
I'd say I got quite a bit out of becoming a fisherman. I feel so sorry for this boy, if this is a real letter, being punished for this is senseless.
