I clicked on this because it had 'guitar' in it but a phrase caught my eye lower down:
"Colin revealed reading about Eric's passion for trains and maps helped him to understand the role a lot better, and he found himself researching trains as well as World War II history.Useful fodder to shove back in the gobs of the garden simperers: I didn't have a role to train for and not a scintilla of interest in the hobby.
He said: "I'm not really a collector of things but I completely admire that passion and devotion to something and a desire to know it and understand it."
Passion and devotion ~ all very commendable but surely not when it spills over into boring and bullying innocent others? I must use and explore this further.
