There are so many sides to this that we could start or join another discussion group about it. There is:
1) the vanity and self importance side
2) the think first-speak later side
3) the ubiquitousness (no one is free of the wish at some time to go back and change or retract things - this may roughly be called remorse)
4) the fatalist side "Nobody listens to me, anyway"
5) the "I will do anything not to see myself as others do" side
6) the "Maybe I need to learn to accept myself as I am more gracefully" side
and on and on.
One reason there are so many lurkers in discussion groups is the fear of putting one's foot in one's mouth. Living one's life passively, vicariously, is valid and permissible, but if everyone did it we'd still all be drinking bad coffee.
So post away, phil2spill and don't look back. We're all hungry to learn from you, and if you forgive us for being tedious overbearing pedantic pompous arses, we'll forgive you.
