This's nice, believe me!
In contribution to the emphasis made on the act of the third servant...
Quoting his words, he said "Master!, I know you to be a hard man, reaping where you did not sow..."
This of cos, might be true of their master, but why would he be the one, out of all other servants, to point that out?
My point... We shouldn't be the bearer of Bad News. Words can mean a lot, when it goes into the right ear at the wrong time..
