Aeronautical Engineer come window cleaner.
I couldn't give a toss what people think of me - if they want to think I'm 'just a window cleaner' thats fine with me, personally I see myself as a businessman in the window cleaning trade - my son gets annoyed sometimes though, people he grew up with who think they are better than him, what they can't see is they are in jobs with no prospects (yes I include solicitors etc in this), they all have to work Mon to Fri for a boss who doesn't give a toss about them, they dedicate their lives to itheir profession - fair enough, at least my son has the sense to realise the more important things in life such as family and not to put too much stress on himself, enjoy life and all it has to offer.
oh nearly forgot - I pay him very handsomely (more than most of his "mates" get), bought him his car (m3 e46) and he will inherit my company when I retire.
would I ever go back to making travelling safer for the masses - never.
