Don !
I can understand you beimg seriously upset and ropable about GMan's
derogatory remarks.
I feel exactly the same way, in fact I had to close my ears, take an
aspro and lie down for half an hour before I could face the world again.
Nevertheless I am glad I have finally found a way to contribute to the
list, namely to be the receptacle for GMan's stresses strains and angst
(all of which must save him a poultice in Anger Management Fees). Once
I had reread his "expletives deleted " and "explosives ignited" again
I felt life was still worthwhile. And apparently he has become a much
better person to live with (I just received an offlist message from his
cats, saying so).
Nevertheless I still think he shd be reported to the Mods??
Roger W
ps when I have fully recovered I will endeavour to reply to the rest of
his message
