There is a cost to not responding, a cost to not doing what you are suppose to do. While you may get away with it for a little while but sooner or later it will catch up with you. Be accountable, lead well, show love through the action of following thru and doing what needs to be done.
So often people don't do the simplest of things. Being accountable is a big one. So often they take the easy road of blaming someone else.
