This was a really interesting comment and one which prompted a bit of a gut reaction.
My response was that everyone deserves a compassionate response and we should only contemplate removing them from our circle of influence after we are comfortable that we have provided such a compassionate response to them.
We all have our negative times in life, for whatever reason, and we all need other people to invest their energy in us at some stage, even if we are usually full of energy ourselves and able to cope with most things in life. When we hit these periods I am sure we would all like to think that we could rely on others to provide us with a bit of a boost, without simply deciding to cut us loose.
For some people it does become clear that no matter how much we invest in them these characters are not going to change and are going to continue to be energy suckers.
It does raise an interesting question though.
What is the threshold for determining that you have done all that you can?
