Thanks, thats put my mind at rest, knowing that I am clearly not "abnormal"

Just one thing though, and excuse me if I am being daft and probably paranoid here, but is there a correct way/order to attach the phone to the charger ? I never even gave it a thought before, but it was suggested by someone else (and I am not suggesting this to be a reliable source) that you should connect the phone to the charger first and then switch on or plug in the charger second. Or is this scaremongering drivel ? Most people I know have the charger plugged in already and just happily connect the phone/laptop whatever without any adverse issue ?
