Don't forget that confidence\trust grows from knowing what your reaction will be, not necessarily the reaction itself. If one day you are mad and the next day try to be nice and calm, this will not bring trust - not because of either reaction but because the reaction wasn't the same.
A horse who gets a whack each time it does something at least knows if I do 'A' then I get a whack.... (please don't jump on the bandwagon and start a discussion on whacking horses - its just an example

)
