If I wanted two new tyres on the Ragsmobile I probably wouldn't pop round to see my mate Albert. At the same time, and no offence intended, if I wanted a discussion on epistemological problems in atomic physics I probably wouldn't be jumping on the first bus down to the local Kwik-Fit. I wouldn't expect a bus driver to be a whizz at portrait painting, but I also wouldn't expect Van Gogh to ask me "how far do you expect to get on fifteen pence and would you like some sunflowers to go with your no standing on the top oi sonny mind your manners next stop Rackhams it'll be a starry night over The Rhone if i catch you messing with the almond blossom".

So have you ever wondered why Bob Dylan became a singer/songwriter ? Nor me !
