Well as I see it, someone took the time to eductate me when I was fishing my local canal with a size 6 meat hook with maggots for bait :O as a kid.
The only way our years of info gets passed on and new people join the sport is by helping and sharing our info with youngsters.
Beginners will only take so many failed attempts before giving up at something and what good are all your best kept fishing secrets after you are dead? Number one priority with this kid was to get him to catch by any means, after that taste im sure finesse will come later!
On a side note there is a fine line between helping someone out and been one of those busy bodies you get that stands next to you imparting every bit of "helpfull knowledge they have".
We all know the type

Hehe we have a bait fisher who has never held a flyrod in his life in our club. Hes a nice enough bloke but he will insist on standing next to ya and saying "oi fella, fella, what ya need is an orange goldhead on" whilst "helping you" by throwing handfulls of casters next to where you flies land!! "There ya go mate, got em on the top for ya now, get yer fly in there!!!" just as you watch that specimen brown youve been stalking melt away and end up replaced by a feeding frenzie of stockies, so preoccupied with caster they wont touch anything else!!!
