The small things count. I managed to get a pregnant woman who is visiting the UK on work a ‘baby on board’ badge for the tube. The gratitude was unexpected. I didn’t know that she’d tried several times and was unable to get one. All I did was to ask at the station and a kind guard said I shouldn’t really hand them out but I’m guessing it’s not for you (he noticed my beard :)) and you look like an honest man. You see kindness does have a ripple effect.
