When I was 15, had a cousin that bought new Suzuki 750cc motorcycle and often he would take me for a ride. To have such bike, was a 'dream' for me. Few years later, bought similar sized bike and had a friend who had the exact bike that my cousin have had. Naturally, we swap them and finally I had an opportunity to drive my 'dream' bike. Than, went to see that my cousin to tell him that story...his answer was: 'do you realise now that such dreams are 'biggus dickus' (as Monthy Python guys would say)
Same sensation with first decent car, or piece of hi fi gear. That feeling is hard to ovecome with new 'toys' now, when we are grown up (well, sort of) which is quite understandable. As one becomes wiser, he understands where 'real' values are, no matter how still great the pleasure might be when enjoying 'trivial' things as 'planes, trains and automibiles', or hi fi systems, for that matter...
