Depending on what sort of lamps/bulbs you have, when you've disconnected the live from the circuit (by operating the MCB), the 'live' feed to a lamp may effectively become a 'neutral' (due to the path through the lamp to neutral) - so touching that to earth could also cause an RCD to trip. That would definitely be the case with 'old-fashioned' filament lamps/bulbs, but with new-fangled ones (energy saving, LED etc.) it 'depends' (on what goes on inside the lamp/bulb).
I am paraniod about electric shocks, after receiving a belter in my early teens Many/most of us have been there, most usually at that sort of stage of life, and it certainly can have a lasting effect on one's attitude to (and respect for) electricity, and therefore one's behaviour!I think all was well
