Yes, similar sitchs can draw us to certain threads, but for me that's not always the attraction. Sometimes it's the poster's good attitude that I admire and draw strength from (e.g. see sunseeker and KAW) - other times I like the practical, no holds-barred approach to a sitch (the great wiley or workinghard) - and finally, I need probing wisdom (provided so well by you, sage).
In fact our sitch's couldn't be more different, but perhaps our situational differences help us to provide one another with "detached" and uncomprimising advice that we may be too clouded within our own sitch's to be able to see for ourselves.
