I think there's a fine line between straight talking and aggressiveness - it can take some skill.
I'm not even sure aggressiveness is the right word tho?
I think that rigour (if we can call it that) most times actually comes from fear...people being genuinely scared for other people.
I think considering the great mix of personalities situations and experiences here, we get it right an amazing percentage of the time.
Sometimes the message is received, sometimes, not...and , often, the message is received by someone else
